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) a042107883
    Only use Gtk::Window::set_default_icon_name method when available (#695279)
 2) b09d6035cd
    Add fallback method for specifying GParted icon (#695279)
 3) d6baac2546
    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
