[libpeas] Use GArgument instead of va_list in peas_extension_set_call()

[Steve Frécinaux <sfre src gnome org>]

commit 83c9a62db4e0df41c80a7166fcd81a53854c308c
Author: Steve Frécinaux <code istique net>
Date:   Wed Sep 1 00:18:46 2010 +0200

    Use GArgument instead of va_list in peas_extension_set_call()
    
    This allows us to drop our G_VA_COPY usage, as we now just pass the
    same GArgument array several times instead.
