dhcp: allow for excluding the external bind

There is a known issue when using ISC DHCP alongside bind 9.10. DHCP uses libraries
provided by bind and there is a bug which results in dhcpd/dhclient not
running in the background and not responding to sigterm.

The issue was first reported in 02/2015 by the fedora team here:

https://lists.isc.org/pipermail/bind-users/2015-February/094636.html

and as of 02/2018 it is still unresolved:

https://bugzilla.redhat.com/show_bug.cgi?id=1457871

Fedora's workaround seems to consist of providing working libraries from the bind 9.9
package just for DHCP.

added 'ext-bind' in PACKACGECONFIG
added notes on how to enable the workaround
refreshed patches too
