iproute2: rename ip to ip-tiny and let both ip-tiny and ip-full provide "ip"

Rename the "ip" package declaration to "ip-tiny" and let both "ip-tiny" and
"ip-full" provide the virtual "ip" package. This allows users to freely choose
the "ip" command variant while other packages can continue to depend on "ip"
without needing to enforce a specific variant.

Note that this commit does not add busybox as "ip" provider due to
the following reasons:

 - The builtin Busybox ip applet cannot be added or removed at runtime
 - Both "ip-tiny" and "ip-full" are able to install without file clashes even
   if the busybox applet is enabled
 - The system is preferring full "ip-tiny" and "ip-full" at runtime, even
   if Busybox ip is still present.
