Different versions of perforce / git appear to use various naming schemes for perforce variables. This fix updates the regular expression to match two known names for the perforce path variable.

Testing was done on a git-p4 checkout using the latest release versions of Git and Perforce, with the latest HEAD of RBTools with this fix applied. The issue described in https://code.google.com/p/reviewboard/issues/detail?id=3169 no longer appears.
