Strip leading / from source paths in classpath

In Gitiles, buck audit classpath returns entries like:
  buck-out/gen/gitiles-servlet/lib__servlet__output/servlet.jar

Prior to this change, matching the provided regex results in a group
like:
  /gitiles-servlet

We then check for the existence of '/gitiles-servlet/src/main' et
al., which of course fails since this looks like an absolute path.

This regex previously didn't capture the leading '/', but was changed
to do so in Ib50d37c1. Now that it does, we need to strip that before
doing any path existence checks.
