Fix repository dir requiring itself: major breakage

Since 67c938e4 $basedir/reponame dir requires itself.

Surprisingly enough that doesn't throw any error or warning, and all resources dependent on it fail silently. So pretty much nothing works anymore.

Just removed that require, problem solved.

PS: Will check out puppet bug tracker to see if anyone already reported this. I had to read debug output line by line to understand what was going on.
