Fix enum generation problems in glib-gen.mak.

Don't use pattern rules like %-enumtypes.h anymore because it matches
installed header files like camel-enumtypes.h, so you get very strange
things happening during the build like:

    .../camel/camel-enumtypes.h: e-util-enums.h
            glib-mkenums ... $^ > $@

when e-util-enums.h has a newer timestamp than camel-enumtypes.h.

Instead, we'll use another variable name -- glib_enum_output -- to
replace the %-enumtypes pattern rules like so:

    $(glib_enum_output).h: $(glib_enum_headers)
            glib-mkenums ... $^ > $@

    $(glib_enum_output).c: $(glib_enum_headers)
            glib-mkenums ... $^ > $@

Also use $(AM_V_GEN) to get cleaner looking output while building.
