commit changes after download patch
Bug: 1203094

anvil use `setup.py develop' to prepare manifest and pack rpm file.
setpy.py in egg_info run "smart" code, which:
- add to manifest .py and .pyc files in ./
- check for version control system
- if found, fetch list of files in current commit and __add__ it
  to MANIFEST
as a result, if download patch remove or move some file, setup.py
still add it to manifest, at package stage try to pack it in rpm and
fail
