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
