[pygobject] Add support for PyBytes with int8 and uint8 from Python marshaler

[Simon Feltman <sfeltman src gnome org>]

commit f517bfbc134b78a23b754332e59b9bb67bb68e98
Author: Simon Feltman <sfeltman src gnome org>

    Add support for PyBytes with int8 and uint8 from Python marshaler
    
    This additional type marshaling is necessary for unifying marhalers
    due to the same feature being available with cached argument marshaling.
