Fix path_utils_ut segfault
In the case where the allocated buffer is not large enough to hold the resulting absolute path, we were writing out a null terminator outside of the buffer, instead of at its beginning. Also fixes potential issue where split_path would not initialize the count to zero if it returned a failure.
