Remove references to suseconfig in profiles and mkinfodir

There are still references to suseconfig in the profiles (/etc/profiles.d/). Three variables seem to be obsolete: CWD_IN_ROOT_PATH, CWD_IN_USER_PATH and SCANNER_TYPE. They are not present in the configuration files read by the profiles, they were probably in suseconfig.

mkinfodir also mentions suseconfig.

Let's clean that.
It happened here:
https://github.com/openSUSE/aaa_base/commit/a49fc250da426eabdb0d1c6bc16a1fe7712358aa

So 12.3, 13.1 and 13.2 didn't have it.  Question is whether we add it back somehow or use the oportunity to silently let the option die. The check for uid > 100 is wrong anyways, user uids start at 500 since ... forever.
