Support '.' in output directory path.

Do not call baseName on the path passed to -o when using the --rendertracks
option. This was mangling directories that contained a literal '.' if a '/' was
not explicitly specified at the end.

Still call baseName for --render as the argument to -o is a file and we need to
set the extension (ogg/wav).
