[pkg] Fix python build issues

. python-script-but-no-python-dep: Because python dependency was
  python2|python3, but bitmask-root has #!/usr/bin/python2.7 the python
  dependency was not being properly resolved. To fix this I changed it to use
  ${python:Depends}

. python-depends-but-no-python-helper: debian/rules needs to call the python
  helper

. missing-build-dependency-for-dh-addon and
  missing-build-dependency-for-dh_-command: added the build-dependency in
  debian/control for python2
