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.

All the implementations of NsecToTimespec and NsecToTimeval were the
same other than types. Write a single version that uses
GOARCH/GOOS-specific setTimespec and setTimeval functions to handle the
types.
The logic in NsecToTimespec and NsecToTimeval caused times before 1970
to have a negative usec/nsec. The Linux kernel requires that usec
contain a positive number; for consistency, we do this for both
NsecToTimespec and NsecToTimeval.
Follow CL 30826 which did the same for syscall.

Analog to the runtime package, Select should be using newselect
instead of select. This change addresses this problem and regenerates
zsyscall_linux_* for ppc64 and ppc64le.

Pause is a legacy syscall not available on linux-arm64. Use ppoll with
all args as 0 to emulate - this is the way musl libc does Pause when the
pause syscall isn't available.
With the changes in syscall_linux* and regenerating zsyscall_linux*,
this calling Pause on linux-arm64 works and returns EINTR as expected.

It wasn't in linux/arm.
Tested with:
$ for x in $(go tool dist list ) ; do \
export GOOS=$(echo $x | cut -d/ -f1); \
export GOARCH=$(echo $x | cut -d/ -f2); \
echo "$GOOS; $GOARCH"; go install .; done
... which all pass, except openbsd/arm which is still broken exactly
how it was broken previously.

arm64 doesn't have a Dup2 syscall, instead Dup3 is supposed
to be used. Since Dup3 is linux-specific, provide a wrapper
to make writing portable code easier.
Updates golang/go#10235
To verify it, added a testcase for Dup and Dup2.
