Improve patch: 601_nx-X11_build-option-changes-to-not-use-bundled-libraries.full.patch. Improvements taken from the current Fedora package. Thanks to Orion Paplowski!!! Also adapt roll-tarball.sh do dropping more bundled libraries.

Change build options so that bundled libraries are not used anymore at build time. Remove bundled libraries from rolled tarballs, as well. (Fixes: #116, #238).
