Bug#258051: FTBFS on kfreebsd-gnu

[Robert Millan <rmh@debian.org>]

Ok, new patch.

The kfreebsd-gnu port is switching to Linux-style procfs, so we want to use
this on dpkg (which works better than our semi-broken libkvm implementation).

I'm keeping the autoconfiscation bits (HAVE_KVM_H) considering they're useful
for other situations, although libkvm is not enabled for kfreebsd-gnu now.

Re-diffed against the 1.13.0 version in experimental.
