dbus: update glib dependency to 2.80

The gpio-manager makes use of g_log_writer_default_set_debug_domains()
which was added in glib 2.80, but the dependency in configure.ac is only
glib 2.54. This results in compile errors when built with glib between 2.54
and 2.80.

Update the glib dependency, and related dependencies, to 2.80.
