    Linux: Register number sysctls only when desperate
    
    The AFS sysctl interface was trying to register numeric system
    calls whenever the kernel would let it. This is anti-social, as
    we've never had sysctl numbers allocated to us. In kernels newer
    than 2.6.24, this misbehaviour is detected and punished. In recent
    kernels, the binary interface has gone away entirely.
    
    Since 2.6.19, the kernel has supported allocated unnumbered system
    calls. These are only available via /proc/sys (and not the using
    the legacy, binary, API), but they're really the only interface
    available to us.
    
    Change the sysctl registration code to use unnumbered calls whenever
    they are available. Unnumbered calls aren't available in 2.4.x, so
    completely remove that code there.
