libvirt is automatically linked to if present, this undetermined
dependency may cause build errors like:
../lib/libvirt.so: undefined reference to `libssh2_channel_open_ex'
../lib/libvirt.so: undefined reference to `libssh2_session_hostkey'
...
Both libvirt and libssh2 are not oe-core recipes for now, just disable
libvirt to fix this issue.
