[libvirt] [PATCHv2 62/62] DO NOT APPLY: Enable QEMU_CAPS_BLOCKDEV if 'query-blockstats' works with -blockdev



'query-blockstats' did not report the 'qdev' field prior to fixing it so
that it works with our setup. Use that as a witness to enable -blockdev

Note that the blockjobs were NOT adapted yet so any blockjob will desync
the state of qemu. This patch needs to wait until blockjobs are fixed.
