[PATCH 4/9] Use virFileFindResource to locate libvirt_lxc for capabilities

["Daniel P. Berrange" <berrange@xxxxxxxxxx>]

From: Nehal J Wani <nehaljw.kkd1@xxxxxxxxx>

Instead of hardcoding LIBEXECDIR as the location of the libvirt_lxc
binary set in the LXC driver capabilities, use virFileFindResource
to optionally find it in the current build directory.
