Move u2f-devd into base?

We have FIDO/U2F support for SSH in base.

We also have a group "u2f", 116, in the default /etc/group file.

Why do we keep the devd configuration (to chgrp the device nodes)
in a port, security/u2f-devd?  Can't we just add this to base, too?
It's just another devd configuration file.
