Undo TEA_PATH_CONFIG changes regarding addtional paths until it's more clear where OpenBSD/FreeBSD stores it's 'official' itclConfig.sh/tdbcConfig.sh.
Fix [923f400aa03a5608]: New paths required for Darwin

adds: This has nothing to do with where any one os stores itcl/itkConfig.sh.

It shouldn't matter to *tclconfig* where any anything stores anything, should it?

This is supposed to be a generic routine, used to pick up the *Config.sh of any extension.

There is no "common store" for *Config.sh files on any platform, afaict.
Extensions currently keep their *Config.sh files in their own dirs. I believe this to be the case currently for all extensions and platforms.
Perhaps changing this convention is a good idea.

The way things are currently, adding dirs for itcl would then mean adding dirs fors tdbc, tdom, etc.?
I don't see that as being viable in the long-term.
