[PATCH 2/2] s3:smbd: add negprot remote arch detection for OSX

[Justin Maggard]

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.
