Fix proc.(*fdDir).IterDirents for VFS2

Currently the returned offset is an index, and we can't
use it to find the next fd to serialize, because getdents
should iterate correctly despite mutation of fds. Instead,
we can return the next fd to serialize plus 2 (which
accounts for "." and "..") as the offset.

Fixes: #3894
