commit c0863d0596ae6b769a29fa3fb72ff036444fd249 (HEAD -> py3)

    Fix codesigningtool.py py3 compatibility.

    In recent versions of plistlib, binary data entries are returned as instances of the built-in bytes class, and plistlib.Data is deprecated.
    Since this script was expecting a plistlib.Data, it would fail with the error "AttributeError: 'bytes' object has no attribute 'data'".
    This change makes it compatible with both new and old versions of plistlib.
