    g_part_ebr: always create "compat" aliases
    
    The "canonical" EBR partition names like `ada0s4+00002081` are not
    particularly meaningful.  The "compat" aliases share the same namespace
    as the parent MBR, resulting in user-friendly names like `ada0s6`.
    These names are consistent with the way Linux names EBR partitions.
    
    We previously provided a sysctl kern.features.geom_part_ebr_compat
    (enabled by default) to control the "compat" names.  Remove the sysctl
    and always create the aliases.
    
    Relnotes: yes
