In u9fs.c, gid2user() may return nil but groupchange() assumes g is
always non-nil. This causes u9fs to seg fault when, for example,
creating a file in a directory that has a group id not defined in
/etc/group. A simple fix is to have groupchange() handle the case
when g is nil:
/sys/src/cmd/unix/u9fs/u9fs.c:1320 a u9fs.c:1321,1322
> if(g == nil)
> return -1;
