The Utsname members are only 32 bytes on Dragonfly and the syscall
returns ENOMEM in case the value is longer than that. Like uname(3)
on Dragonfly, handle this case gracefully and just truncate the
value.

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.

Update go to 1.9.2 in the Dockerfile used to generate the Linux go files.
The update also changes some zerror definitions: RLIM_INFINITY is
assigned to Rlimit.{Cur,Max} which are both uint64 on all architectures.
PR_SET_PTRACER_ANY is used with Prctl which expects an uintptr.
With the current version, an "constant -1 overflows uint64" error would
result if these constants were used directly without type conversion.
