sync: Added --filter=blob:none for git clone of superproject.

Browse Source 
+ This is without --depth option. This is done for reachability.
  Server doesn't know what you know about in the history so it always
  sends you the whole thing Which is very slow.

  If we have the full history it can send you incremental update history
  which is very small and fast.

Tested the code with the following commands.

$ ./run_tests -v tests/test_git_superproject.py
$ ./run_tests -v

Tested the sync code by copying all the repo changes into my Android
AOSP checkout and doing a repo sync --use-superproject twice.

.../WORKING_DIRECTORY$ repo sync --use-superproject
