glib-compile-resources: Add --generate-phony-targets flag

Browse Source 
This includes phony targets for each dependency in the the generated
dependency file which allows building with `ninja` which doesn't like
the phony targets[1] but also allows silencing `make` errors similar to
gcc's -MP option.
