pre-lib9p servers: fix incorrect Tversion handling
version(5) says:
If the server does not understand the client's version
string, it should respond with an Rversion message (not
Rerror) with the version string the 7 characters
``unknown''.
Pre-lib9p file servers -- all except cwfs(4) -- do return Rerror.
lib9p(2) follows the above spec, although ignoring the next part
concerning comparison after period-stripping. It assumes an
Fcall.version starting with "9P" is correctly formed and returns
the only supported version of the protocol, which seems alright.
This patch brings pre-lib9p servers in accordance with the spec.
