    sysutils/bsdfan: print better error message when failing to start
    
    On non-ThinkPad laptops, or when acpi_ibm(4) module is not loaded,
    the program emits cryptic "bsdfan: Not enough permissions: No such
    file or directory" error message.  Replace it with something more
    meaningful and helpful.
