vfs: Remove smb_traffic_analyzer

Holger Hetterich told me in a personal email that he does not have
time to care about this project anymore and that he is fine to
remove it from Samba.

Why the removal? It contains homegrown crypto that would need to
be thoroughly audited and/or fixed. And if it's neither maintained
nor widely used I'd rather have it removed.
