Use .DEPS.git instead of DEPS

This commit is allow developers get GIT version of dependencies.

Most of dependencies in <release_dir>/DEPS are pointing to subversion.
Unfortunately, svn command behind firewall randomly fails with error

Since upstream is switching SVN to GIT, it is time to switch to
GIT(.DEPS.git) totally.
