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.

In commit "7e44b69 x/sys/unix: fix invalid syscall on linux/arm"
a test was added for time/utime syscall. This test exposed that
neither time/utime work on arm64, because they call the legacy
syscall "utimes". As a new architecture, arm64 doesn't implement
any legacy syscalls.
Implement by first calling utimensat, using UtimesNano as exampple.

Updates #11918
Replace calls to lchown(2) with fchownat(2) for linux/arm64 as the former
is not suppored.
This is a companion to CL 12833 which is ready to be applied to the main
repo, and verified by CL 12834 which can be applied once this change and
CL 12833 have landed.

Go1.4 does not recognize arm64 and ppc64le as valid GOARCH values, so
we need explicit build tags.
