[gparted] Raise minimum required glibmm version to 2.14.0 (#794253)

[Curtis Gedak <gedakc src gnome org>]

commit 07f58ed82bca9d7d6e01516206cfa46b919222a6
Author: Mike Fleetwood <mike fleetwood googlemail com>

    Raise minimum required glibmm version to 2.14.0 (#794253)
    
    Increase the minimum required version of glibmm to 2.14.0, thus allowing
    removal of the HAVE_GLIB_REGEX autoconf definition and associated
    conditional code.  This is reversing commit, except for the new glibmm
    minimum check:
    
        456932846bfbfbd77bbf49165b9eb6c2b84e0da6
        Implement fallback if Glib::Regex class is missing (#695279)
    
    Bug 794253 - Desupport RHEL / CentOS 5 and raise minimum required
                 versions to glibmm 2.14.0 and gtkmm 2.16.0
