Add CHECK_FOR_INTERRUPTS into pg_numa_query_pages
Querying the NUMA status can be quite time consuming, especially with
large shared buffers. 8cc139bec34a called numa_move_pages() once, for
all buffers, and we had to wait for the syscall to complete.
But with the chunking, introduced by 7fe2f67c7c to work around a kernel
bug, we can do CHECK_FOR_INTERRUPTS() after each chunk, allowing users
to abort the execution.
