Switch breakpad DEPS to new Git repo URL.
Switch breakpad DEPS to new Git repo URL.

Breakpad is migrating to Git, and we won't be able to git-svn-export
its src/ directory. Instead we'll be using gsubtreed service to extract
src/* subtree from breakpad/breakpad git repo into breakpad/breakpad/src repo.

This CL changes DEPs to use new repo (at the same commit). Git hashes
are different because gsubtreed produces commit messages that are
different from git-svn exporter.
