    tests: Don't test invalid aligned allocations if avoiding UB
    
    We can't exercise precondition check failures if GLib was (inadvisably)
    compiled with -Dglib_checks=false, and we shouldn't necessarily exercise
    precondition check failures when using QA tools like valgrind, so skip
    these tests if run with -m no-undefined.
