Correct the patch for the NTLM helper vulnerability according

to <http://www.squid-cache.org/bugs/show_bug.cgi?id=998>

Apply some cleanups:
 + prefer PATCHDIR over FILEDIR when referring patches
 + remove unnecessary quotes
 + move all substitution tasks to the post-patch target
 + use "${FALSE}" instead of "exit 1" to generate error 1 from a shell
