BUG/MINOR: http-ana: fix NTLM response parsing again

Browse Source 
Commit 9df188695f ("BUG/MEDIUM: http-ana: Handle NTLM messages correctly.")
tried to address an HTTP-reuse issue reported in github issue #511 by making
sure we properly detect extended NTLM responses, but made the match case-
sensitive while it's a token so it's case insensitive.

This should be backported to the same versions as the commit above.
