scripts/spdxcheck.py: always open files in binary mode
The spdxcheck script currently falls over when confronted with a binary file (such as Documentation/logo.gif). To avoid that, always open files in binary mode and decode line-by-line, ignoring encoding errors. One tricky case is when piping data into the script and reading it from standard input. By default, standard input will be opened in text mode, so we need to reopen it in binary mode. The breakage only happens with python3 and results in a UnicodeDecodeError (according to Uwe).
