- remove unnecessarily added patches from SLE11:
* util-linux-update-default-commit-interval.patch, openSUSE has
never changed the default and neither will SLE12
* sfdisk-warn-about-2TB-limit.patch, fixed by upstream years ago
* umount-avoid-readlink.patch, this patch only affects unused
code and the used code does not have this bug
- edit util-linux-lscpu-improve-hypervisor-detection.patch to not
change the default behaviour of "lscpu -p" as documented in it's
man page. Now this patch only affects the summary output.
