    sysctl: Panic on OID reuse
    
    In CheriBSD we had a conflict in the KERN_PROC OID space and didn't
    notice for some time.  Let's panic instead to make such conflicts easier
    to detect.  Note that this doesn't affect conflicts arising from name
    collisions in OID_AUTO sysctls, which happen sometimes due to driver
    bugs.
