s3:smbd: add negprot remote arch detection for OSX
Remote arch detection for OSX clients has been broken for some time, since
both Samba and OSX started supporting SMB2. Fix it by adding modern OSX
client detection support to the negprot remote arch detection routine.

s3:smbd: rework negprot remote arch detection
Negprot remote arch detection is very cryptic. Rework it so it's easier
to understand, and therefore more extensible, following the protocol table
in inline comments. This also allows us to remove some hacks.
