David Lechner f1b6e6bb15 unix/modos: Implement putenv and unsetenv to complement getenv.
CPython also has os.environ, which should be used instead of os.getenv()
due to caching in the os.environ mapping.  But for MicroPython it makes
sense to only implement the basic underlying methods, ie getenv/putenv/
unsetenv.
