On some builders TestStatx occassionally fails when comparing atime
between Statx and Stat/Lstat.
--- FAIL: TestStatx (0.00s)
syscall_linux_test.go:365: Statx: returned stat atime does not match Lstat
Fix it by dropping the atime comparison, it's enough to verify Statx
working correctly by comparing ctime and mtime. Also, not all
filesystems support atime.

The mkfifo syscall is disallowed on android and iOS. sched_setaffinity
is disallowed on android. Skip all tests which use them.
/usr/bin does not exist on android. Use /system/bin in TestGetwd
instead, like TestChdirAndGetwd in the os package.
Like linux, android does not support Fchmodat with flags != 0. Adjust
TestFchmodat accordingly.
TestDevices might stat some device files which are not accessible, skip
those.
iOS cannot exec subprocesses, thus skip TestPassFD.

Now that Fchmodat is available on all Unices, move TestFchmodat to
syscall_unix_test.go and adjust it such that Fchmodat with
AT_SYMLINK_NOFOLLOW in flags is tested where supported.

statx(2) allows to get enhanced file status information (not currently
available through the existing stat syscalls), lightweight stat,
heavyweight stat. The Statx_t type used by Statx has consistent field
sizes on all arches (with year-2038-capable timestamps) and is closer to
the BSD implementation of Stat_t.
See http://man7.org/linux/man-pages/man2/statx.2.html for details. The
syscall was added in Linux kernel 4.11.
See https://github.com/tklauser/statx for an example of how this
function and types can be used to report stat(1)-like file status
information.

Looks like it's enough to just add wrappers pointing to the
corresponding SYS_FSTATAT{,64} or SYS_NEWFSTATAT syscall. Add a test to
verify that assumption which checks that the returned stat data matches
what is returned by Stat/Lstat.
Also add the AT_NO_AUTOMOUNT constant which may be used for the flags
parmeter.

Also add a test on Linux for Uname and the string conversion of the
Utsname members.

Currently Linux' fchmodat(2) syscall implementation doesn't support the
flags parameter (though it might in future versions [1]). Fchmodat in
x/sys/unix takes the parameter and (wrongly) passes it on to the syscall
which will ignore it.
According to the POSIX.1-2008 manual page [2], AT_SYMLINK_NOFOLLOW is
the only valid value for the flags parameter and EOPNOTSUPP should be
returned in case changing the mode of a symbolic link is not supported
by the underlying system. EINVAL should be returned for any other value
of the flags parameter.
[1] https://patchwork.kernel.org/patch/9596301/
[2] http://pubs.opengroup.org/onlinepubs/9699919799/functions/chmod.html
Change the Fchmodat implementation accordingly and also add the
corresponding test.

This CL adds basic integer get/set functions which wrap a generic
ioctl call. The API is similar the one introduced for solaris/amd64
in CL 14587, but the request parameter has been changed to a uint
instead of an int. This makes requests with a number larger than the
maximum signed 32-bit integer work on linux/386.
For consistency, the solaris/amd64 API has also been updated to make
use of a uint instead of an int for the request number.
