[libgsystem] build: Allow callers to control whether or not we are installed

[Colin Walters <walters src gnome org>]

commit 6956ab38077c65ffda21c30bcc4adee2d4826146
Author: Colin Walters <walters verbum org>
Date:   Thu Nov 29 17:58:35 2012 -0500

    build: Allow callers to control whether or not we are installed
    
    And add some more flags to help with that, ensure we're not leaking
    symbols, etc.
    
    This will require static users to add noinst_LTLIBRARIES += libgsystem.la
    to their Makefiles.
