[Buildroot] [PATCH v2] python-protobuf: update dependencies

[Alexey Roslyakov]

Since version 3.0.0 protobuf is compatible with Python3, remove
Python2-only dependency.

It depends on python-six now, add this missing dependency.

Changes v1 -> v2:
  - just remove "depends on BR2_PACKAGE_PYTHON" (suggested by Yegor)
