trans: make the fakeroot environment more transparent

Previously fakeroot did not explicitly proxy io_identity requests, so
the default implementation from libnetfs handled them. But as the fsys
identity port returned was always netfs_fsys_identity, this broke the
getcwd logic (assuming /media/scratch is a translator):

% cd /media/scratch/foo && fakeroot-hurd pwd
/foo

Fix this by proxying io_identity requests. Since then no-one is
handing out our netfs_fsys_identity port anymore, an optimization in
netfs_fsys_identity is made obsolete by this change.

* trans/fakeroot.c (netfs_S_dir_lookup): Adjust code accordingly.
(netfs_S_io_identity): New function.
