    syscall.master: Fix comments
    
    Have more accruate comments. While #if, #else, etc are copied to the
    header files, lines that don't start with # are not.  And #include files
    are only output to sysinc (which winds up at the front of init_sysent.c
    which seems a bit odd). This is all radically undocumented, and likely
    has drifted somewhat from 4.4BSD and what other systems do (they've
    drifted too, fwiw).
