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.
