[libvirt] [PATCH] Fix a compilation problem with LXC drop capabilities

The lxcContainerDropCapabilities() function requires PR_CAPBSET_DROP to be defined in order to compile, but it may not be defined in older kernels. So I made the compilation of the core of the function conditional, raise an error but still return 0 to not make the container initialization fail. But I'm unsure, should we just fail and return -1 if we can't drop capabilities instead ?
