unix/main: Print usage and NLR errors to stderr instead of stdout.

Browse Source 
When stdout is redirected it is useful to have errors printed to stderr
instead of being redirected.

mp_stderr_print() can't be used in these two instances since the
MicroPython runtime is not running so we use fprintf(stderr) instead.
