colord fails to build if libgusb was built without gobject-introspection support

[tgurr]

Since it's last release libgusb can be built without gobject-introspection support again, that feature was lost with the translation to the meson build system. The same is true for colord which before the migration to meson also allowed to be built without gobject-introspection via a configure flag.

It would be nice if a build option for gobject-introspection support could be added to the meson build again for colord as well.
