update plan9/u9fs to 20210125

This switches plan9/u9fs to another upstream which has seen some small
development over the time, following what other package repositories
already did: https://bitbucket.org/plan9-from-bell-labs/u9fs

port-wise:

 - tweak the COMMENT
 - drop unneeded patches
 - install u9fs in sbin/ rather than bin/
 - install the manpage (and tweak it so it's useful in here.)
