Unpack should uncondititionally initialize fc.Unamenum

[GoogleCodeExporter]

Srv.attach uses Unamenum to determine if user lookup should be done by uid. if 
left uninitialized in non-dotu mode, a user lookup will be done by uid for uid 
0 in Srv.attach, when the lookup should be done by username.

the fix i believe would be to initialize fc.Unamenum to p.NOUID unconditionally.
