[bug#48028] [PATCH wip-gnome v5 2/8] gnu: gtkmm@2: Override inheritance of certain changes from gtkmm.

[Raghav Gururajan]

Recent changes made to gtkmm (d7974adbed019160c10036b040e8d9ff789cbc26),
are not applicable to gtkmm@2, as the latter does not use meson.

* gnu/packages/gtk.scm (gtkmm-2)[build-system]: New field.
[arguments]: New field.
