[gjs/wip/imports-rewrite: 4/5] context: Move gjs_get_search_path to here

[Jasper St. Pierre <jstpierre src gnome org>]

commit d4b8115affa6dd6c42b0073c83e6f1a54431c774
Author: Jasper St. Pierre <jstpierre mecheye net>
Date:   Wed Jun 17 16:38:06 2015 -0700

    context: Move gjs_get_search_path to here
    
    ... and make it public. This will be used by the JS imports system,
    since we'll be removing the old C++ one.
