Using a 'choice' here is not a good idea. Selecting something in a 'choice'
does not work properly.
Is there any good reason to keep the old version? If not, then just replace
it. Otherwise leave the old packages as is and add a new netcat-bsd
package. Just make things exclusive as we do with busybox tools.

I don't think this is necessary. As far as I know, there are no
prerequisites. The packages should build anyways but using IPv6 may not
work during runtime.
