Clean up clean_old():

* Remove syspatch files from the installed system and not the ramdisk.
* Directly try to remove the old files without superfluous check.
* Use an extended glob to match /usr/lib/gcc-lib contents that don't
belong to this OS version.
* For /usr/lib/clang, set an array to the expansion of the glob, which is
an alphabetically sorted list, drop the last element, and rm the rest.
