Disallow "trusted" namespace xattr in VFS2 gofer client.
Allowing this namespace makes way for a lot of GetXattr RPCs to the gofer
process when the gofer filesystem is the lower layer of an overlay.
The overlay filesystem aggressively queries for "trusted.overlay.opaque" which
in practice is never found in the lower layer gofer. But leads to a lot of
wasted work.
A consequence is that mutable gofer upper layer is not supported anymore but
that is still consistent with VFS1. We can revisit when need arises.
