QTemporaryFile: hide the O_TMPFILE feature behind a check for linkat()
Some Linux libc (I'm looking at you, Bionic) use the system call but
don't expose it to userspace. We could use syscall() to make the system
call, but instead I decided to penalize users of those libc by not
having the feature.
It's probably a good thing, since there were likely to be more problems
with Android anyway and I don't have an environment to debug.
