[PATCH 2/3] vhost-user-blk-server: depend on CONFIG_VHOST_USER |

I interpreted CONFIG_VHOST_USER as controlling only QEMU's vhost-user
device frontends. However, virtiofsd and contrib/ vhost-user device
backends are also controlled by CONFIG_VHOST_USER. Make the
vhost-user-blk server depend on CONFIG_VHOST_USER for consistency.
Now the following error is printed when the vhost-user-blk server is
enabled without CONFIG_VHOST_USER:
$ ./configure --disable-vhost-user --enable-vhost-user-blk ...
../meson.build:761:8: ERROR: Problem encountered: vhost_user_blk_server
requires vhost-user support
