escape() in aa.py is broken

[Jakub Wilk]

The escape() function in utils/apparmor/aa.py is completely broken.
It tries to use a malformed regular expression, resulting in:

    sre_constants.error: missing ), unterminated subpattern at position 0

The function doesn't seem to be used anywhere, so it should be probably removed.

This bug was found using pydiatra:

Thanks for the report!

You are right that the function is unused (I have a
    raise Exception("dead code walking")
in it since some months ;-) and grep also didn't bring up any usage of it)

I just sent a patch to the mailinglist that removes the function.
