[PATCH v2 4/6] tests/qtest/vhost-user-blk-test: Setup MSIx to avoid error on aarch64

[Eric Auger]

When run on ARM, basic and indirect tests currently fail with the
following error:

ERROR:../tests/qtest/libqos/virtio.c:224:qvirtio_wait_used_elem:
assertion failed (got_desc_idx == desc_idx): (50331648 == 0)
Bail out! ERROR:../tests/qtest/libqos/virtio.c:224: qvirtio_wait_used_elem:
assertion failed (got_desc_idx == desc_idx): (50331648 == 0)

Setting up and enabling MSIX fixes the issue.

Also remove the useless libqos/libqos-pc.h header inclusion.
