afs: Make /afs/@cell and /afs/.@cell symlinks

Make /afs/@cell a symlink in the /afs dynamic root to match what other AFS
clients do rather than doing a substitution in the dentry name.  This has
the bonus of being tab-expandable also.

Further, provide a /afs/.@cell symlink to point to the dotted cell share.
