pep8: Ignore W504 and W605 to silence warnings on Debian
    
    This code:
        pkcs11_txt.write("library=libsoftokn3.so\nname=soft\n" +
                         "parameters=configdir='sql:" + config.ABS_BUILDDIR +
                         "/../test_CA/p11_nssdb' " +
                         "dbSlotDescription='SSSD Test Slot' " +
                         "dbTokenDescription='SSSD Test Token' " +
                         "secmod='secmod.db' flags=readOnly)\n\n")
        pkcs11_txt.close()
    
    Was producing warnings such as:
    ./src/tests/intg/test_pam_responder.py:143:22: W504 line break after binary operator
    
    Even though it looks OK visually and conforms to pep8's written form.
    
    Additionaly, this regular expression compilation:
     Template = re.compile(
                ' *<template name="(\S+)">(.*?)</template>\r?\n?',
                re.MULTILINE | re.DOTALL
            )
    
    Was producing a warning such as:
    ./src/sbus/codegen/sbus_Template.py:156:29: W605 invalid escape sequence '\S'
    
    Since the \S literal is part of a regular expression, let's suppress
    this warning as well.
