[packages/{e2fsprogs,util-linux,util-linux-ng}] update/rename those packages

This patch makes several changes to the util-linux(-ng) package:
 * rename to util-linux (official name now, util-linux-ng got merged)
 * bump to last stable version 2.21.1 (was 2.13.0.1 before)
 * add several new packages
 * sort packages within Makefile
 * remove patches which got merged upstream

This patch makes some changes to the e2fsprogs package:
 * bump to last stable version 1.42.2
