rename function for finding classifier settings

Prior to this commit, the full path that r10k needed to untar was
more than 100 characters for the classifier settings function

After this commit, it should be just short of 100 characters
so it works around PUP-5994 before we can get the resolution in
puppetlabs/forge-ruby#27
