cmake: check for the necessary symbols for test-segfault.c

If we don't check for them, and you have core dumps enabled, then
running this test under cmake is really annoying, because it leaves
lots of core dumps none of which are actually a problem.

The equivalent Autotools change (which added the actual code that
this relies on) is commit ae50d46, from fd.o#83772.
