Subject: [PATCH] libvirt: use pkg-config to locate libcap

libvirt wants to use pcap-config to locate the exisence and location
of libpcap. oe-core stubs this script and replaces it with pkg-config,
which can lead to the host pcap-config triggering and either breaking
the build or introducing host contamination.

To fix this issue, we patch configure to use 'pkg-config libcap' to
locate the correct libraries.
