test-prio-queue: use xmalloc

test-prio-queue.c doesn't check the return value of malloc, and could
segfault.

It's unlikely for this to matter in practice; it's a small allocation,
and this code isn't even installed alongside the rest of Git. But let's
use xmalloc(), which makes auditing for other accidental uses of bare
malloc() easier.
