tests: Build virtiofsd from specific branch

In order to be able to use the latest version from virtiofsd binary, the
integration tests will now build it directly from a branch located on
sboeuf's QEMU fork. The same way the kernel is hosted on sboeuf's linux
kernel fork, this allows to update the version of the virtiofs daemon
based on latest patches from virtio-fs maintainers.
