[gparted] Increase minimum required gtkmm to 2.11.1 (#794253)

[Curtis Gedak <gedakc src gnome org>]

commit 0ab2adb67fd3ef8e75698c596245b81762b8c7c2
Author: Mike Fleetwood <mike fleetwood googlemail com>
Date:   Wed Mar 7 13:09:35 2018 +0000

    Increase minimum required gtkmm to 2.11.1 (#794253)
    
    Increase the minimum required version of gtkmm to 2.11.1, thus allowing
    removal of:
     *  HAVE_SET_DEFAULT_ICON_NAME autoconf definition and associated
        optional code.
     *  INSTALL_PIXMAPS_DIR automake conditional and associated make
        instructions.
    
    This is reversing these 3 commits, except for the higher minimum gtkmm
    version:
     1) a04210788399736ff7f097cb75650ebcbd0a4950
        Only use Gtk::Window::set_default_icon_name method when available (#695279)
     2) b09d6035cdca90debb145628b0c62a0213ee1225
        Add fallback method for specifying GParted icon (#695279)
     3) d6baac254677b7863af413a38f382e9a2e0252bd
        Only install fallback icon when required (#695279)
    
    Bug 794253 - Desupport RHEL / CentOS 5 and raise minimum required
                 versions to glibmm 2.14.0 and gtkmm 2.16.0
