    Annotate geom_md with MODULE_VERSION
    
    This was missed in 74d6c131cbe2 where other geom modules were annotated
    with MODULE_VERSION.  Again, the problem is the same: we can't detect
    that geom_md is loaded into the kernel without it.
    
    This was noticed in release builds on the cluster; mdconfig attempts to
    load geom_md because it can't detect it in the kernel, but the cluster
    config includes md(4) and does not build the kmod.  This problem would
    have been masked on hosts with the kmod built, as the kmod attempts to
    register the g_md module and fails.  With this commit, mdconfig would
    not even try to load it again.
    
    (cherry picked from commit b9c92d631cfb06c12b0d2d9ad29a9f3f0b856237)
