Subject: [PATCH] Handle %post scripts that contain non-ascii characters

when running LC_ALL=C and python3 this otherwise traces with:

  File "rpmlint/PostCheck.py", line 83, in check_syntax_script
    tmpfile.write(script)
UnicodeEncodeError: 'ascii' codec can't encode character '\xfc' in position 16: ordinal not in range(128)

Add test coverage.
