[meta-virtualization][PATCH] libvirt: disable netcf backend by default

I see a failure in netcf:
| ./bootstrap: .gnulib/gnulib-tool  --import --no-changelog --aux-dir build-aux --doc-base doc --lib libgnu --m4-base gnulib/m4/ --source-base gnulib/lib/ --tests-base gnulib/tests --local-dir gl  --lgpl=2 --with-tests --makefile-name=gnulib.mk --libtool --import ...
| python3: can't open file '/home/flk/bitbake-builds/poky/build/tmp/work/corei7-64-oe-linux/netcf/0.2.8+git/sources/netcf-0.2.8+git/.gnulib/.gnulib-tool.py': [Errno 2] No such file or directory
| ./bootstrap: gnulib-tool failed

Since the code hasn't been updated in over seven years, and after reading this discussion, perhaps the best solution would be to disable netcf support by default?
