[glib] Fix the mapping test in continuous

    Fix the mapping test in continuous
    
    It turns out that due to a recent gdm change, the inherited
    signal mask has SIGUSR1 blocked - which is bad news for
    tests using SIGUSR1. Fix the test by explicitly checking the
    signal mask before using SIGUSR1.
