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.
hmm, I'm not sure it was intentional that no sysconfig file provides those settings anymore.
