[issue28114] parse_envlist(): os.execve(), os.spawnve(), etc. crash in Python 3.6.0 when env contains byte strings

Thanks for the spawn test framework, Victor. I've added a use_bytes argument to encode the args and env using os.fsencode. It's encoding args as well because parse_arglist calls fsconvert_strdup, which was assuming Unicode strings on Windows instead of first calling PyUnicode_FSDecoder. test_spawnve_bytes passes for me on Linux and Windows.
