Make pg_numa_query_pages() work in frontend programs

It's currently only used in the server, but it was placed in src/port
with the idea that it might be useful in client programs too. However,
it will currently fail to link if used in a client program, because
CHECK_FOR_INTERRUPTS() is not usable in client programs. Fix that by
wrapping it in "#ifndef FRONTEND".
