    sudo: improve reproducibility
    
    Delete various build host references from the internally
    generated file sudo_usage.h. The references get compiled into
    executables, which leads to non-reproducible builds.
    The removed references (configure options) were only used as part
    of the sudo "usage", and even then only when ran as root.
