x/sys/unix: add support for O_TMPFILE in Linux
Since Linux 3.11, O_TMPFILE flag can be used in open syscall to create
an unnamed file in a directory. The file occupies space in the
filesystem, and can be given a name using linkat syscall. If the file is
closed without being given a name, its contents are deleted.
See the manpage open(2) in Linux for details.
Exports O_TMPFILE for Linux in 386 and amd64 (other architectures
already had it). Exports Linkat syscall and AT_SYMLINK_FOLLOW (used for
giving a name to the file) for all Linux in all architectures.
Fixes golang/go#7830.
