localmodconfig: Document localmodconfig in README

Someone (over a year ago :-p) asked me to document localmodconfig in the
README file in the source code.  I thought it was a good idea but other
things were more important and I simply forgot about it.  Well, I
stumbled on the email asking me about this and I'm sending it out now.
