python/machine.py: Don't modify state in _base_args()
Don't append to the _remove_files list during _base_args; instead do so
during _launch. Rework _base_args as a @property to help facilitate
this impression.
This has the additional benefit of making the type of _console_address
easier to analyze statically.
