[pangomm] Allow other modules to use the m4 files.

[Murray Cumming <murrayc src gnome org>]

commit 20935b3d57dda84dfea3a9e11950a36f895ab5dd
Author: Murray Cumming <murrayc murrayc com>
Date:   Fri Jan 7 23:33:53 2011 +0100

    Allow other modules to use the m4 files.
    
    	* codegen/Makefile.am: Install the m4 files, like gtkmm installs its files.
    	* pango/pangomm.pc.in: Add the gmmproc4mdir variable so that other modules such
    	as gtkmm and cluttermm can get the path to the m4 file, to avoid
    	duplicating its contents.
