By default, only python dependencies are added to the depfile. If there are
other input paths that are not captured by GN deps, then they should be listed
in depfile_deps. It's important to write paths to the depfile that are already
captured by GN deps since GN args can cause GN deps to change, and such
changes are not immediately reflected in depfiles (http://crbug.com/589311).
