Remove references to suseconfig in profiles and mkinfodir

There are still references of suseconfig in the profiles (/etc/profiles.d/). Three variables seem to be obsolete: CWD_IN_ROOT_PATH, CWD_IN_USER_PATH and SCANNER_TYPE (there are not present in the configuration files read by the profiles, they were probably in suseconfig).

mkinfodir also mentions suseconfig.

Let's clean that.
