util/vhost-user-server: use static library in meson.build

Don't compile contrib/libvhost-user/libvhost-user.c again. Instead build
the static library once and then reuse it throughout QEMU.

Also switch from CONFIG_LINUX to CONFIG_VHOST_USER, which is what the
vhost-user tools (vhost-user-gpu, etc) do.

[Added CONFIG_LINUX again because libvhost-user doesn't build on macOS.
