[PATCH rtems-source-builder v1] source-builder: Handle utf8 in path

[Kinsey Moore]

It's possible for an environment to have unicode characters in its
paths. This was recently exposed by the latest newlib update and RSB
fails under Python 2.7 in this situation. This resolves the issue by
ensuring that the paths are encoded and decoded as necessary.
