Convenience tool for rolling git-style deps with an svn revision.

Usage: roll-dep third_party/WebKit 12345

That will update DEPS with the new revision, and leave the DEPS file
dirty.  It's the up to the user to 'git add; git commit;
git cl upload'.

This script won't handle arbitrary python syntax, but it will handle
variable references like Var("webkit_revision") correctly.
