net-snmp: Enable MIB ip-mib/inetNetToMediaTable

This enables the table `inetNetToMediaTable` from `ip-mib`, which implements
the `ipNetToPhysicalTable`. The former one is already enabled with the current
configuraiton, but it has been deprecatd by the IP version-neutral
`ipNetToMediaTable`, which also supports IPv6 entries [1]. It also disables all
other submodules from this MIB to keep the footprint small.
