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.
> Beside this if one removes the code for the (t)csh shell than I'd like to ask for the bource (again) shell code as there as well CWD_IN_ROOT_PATH and CWD_IN_USER_PATH are handled.

I have removed CWD_IN_*_PATH in bash profile as well.

> Nevertheless we loose (again) a major SUSE feature here.

I consider we have already lost this feature, because it doesn't work and nobody has tried to fix it, afaik. Moreover, I don't think it's a major feature, but that's just my opinion.

However, I would be happy to try to readd this feature, if you think it's useful, but not in this pull request. I'd just like to clean things here (/etc/sysconfig/suseconfig needs to be removed from the list of configuration files anyway).

So if I just revert changes about CWD... variables in this pull request, would it be OK?
