Bug#1125958: libguestfs: uses obsolete, to be removed isc-dhcp

[Hilko Bengen]

control: tag -1 -patch

Bastian,

I appreciate the effort, but the patch that simply removes the
build-dependency is not quite sufficient. Please don't NMU, I'll take
care of the problem before the package is automatically removed.

Cheers,
