Add mask flags to GIMarshallingTests to test for flags with the same …

…value.

Glib uses flag aliases, multiple flag names with the same int
value. For example G_IO_FLAG_MASK and G_IO_FLAG_GET_MASK. We need
these flag values to test that gi bindings don't assume that all
flags have the same value.
