[libvirt] [PATCH] rpm-build: use pkg-config to detect wireshark presence

Wireshark supports pkg-config since 1.11.3. Right now we build wireshark-dissectior tool as default trough rpm build only on fedora >= 21 and there is newer wireshark that supports pkg-config. If someone wants to build libvirt with wireshark-dissector against older wireshark, they should specify the location by hand. This patch is mainly to fix wrong dependency on wireshark binary as it doesn't make sense to require that binary file to just get version info of that package in makefile.
