lib: add test for igt_fork_signal_helper

Browse Source 
If we're really fast we've trying to stop the signal helper again
we somehow race somewhere and it'll never happen. So add a testcase for
this. Since I expect more to come for testsuite tests add a separate
make target for them. Run tests with

$ make check
