mtest: Don't use thread executor when enabled gdb in test_setup

If the global gdb option of mesontest is disabled (e.g. not set '--gdb')
and the gdb option of test_setup is enabled, an exception will be thrown.

Because signal.signal function can only be called from the main thread.
If attempting to call it from other threads will cause a ValueError exception to be raised.
