Enrico Weigelt, metux IT consult 63a635b7bf test: add XLIBRE_TEST env var to select which unit test suites run
run_test_in_child() now checks XLIBRE_TEST (a comma-separated list of
suite function names, e.g. "ddc_tests,xkb_test") and skips any suite
not named in it. Unset/empty behaves exactly as before (run
everything).

Handy for iterating on a single new test suite without wading through
the rest of test/tests' output every run, and for isolating one
suite when an unrelated one in the sequence is flaky (run_test_in_child
exit()s the whole binary on the first failing suite, so a single flaky
suite ahead of the one you care about currently blocks everything
after it).
