[glib: 1/2] tests: Skip assert-msg-test.py if gdb is non-functional

[Emmanuele Bassi <ebassi src gnome org>]

commit 6e44151bf74d6afa2211d76c07164ee810368b29
Author: Philip Withnall <pwithnall endlessos org>

    tests: Skip assert-msg-test.py if gdb is non-functional
    
    Some of the CI runners disable ptrace, as they’re running inside a
    container and ptrace would allow container escape. On those systems, gdb
    can’t work, so skip the gdb test.
    
    Add some additional stderr debug output to make it clear that’s the
    case.
