It turns out that we have unistd.h for some architectures but not
others.  We are thus unable to use e.g. usefaultfd on these systems.

Fix up update-linux-headers.sh to make sure we
get it for all architectures which have linux-headers/
(unfortunately this still does not mean "all linux systems").

Tested on x86 only.

Pls consider merging this through the migration tree.

Cc MIPS maintainers.
Can we drop the MIPS blacklist for kvm?
Could you guys pls check?

My guess is that MIPS got blacklisted in 1842bdfdbac2ec4
because Marc-André didn't want to deal with the fact that
the mips unistd.h includes another header that would also
need to be synced. Marc-André, I don't suppose you can
remember your reasoning from three years back? :-)

thanks

Reviewed-by: Dr. David Alan Gilbert <dgilbert@redhat.com>

and queued for migration;  I'll test build Power and aarch64 as well.
