mpy-cross/mpy_cross: Fix default path to mpy-cross binary.

Browse Source 
Needed to be updated to use build/mpy-cross.

Also fixes some other issues in the Python wrapper:
 - Rename find_mpy_cross_binary to _find_mpy_cross_binary
 - Fix passing of -march arg.
 - Decode stdout from subprocess.
 - Print stdout from mpy-cross in __main__.py.
