    base-files: ipcalc.sh: use shebang to invoke awk
    
    There's hardly an shell logic in ipcalc.sh and a $* that would garble
    parameter positions.
    Move the awk invokation to the shebang.
    
    A rename from "ipcalc.sh" to "ipcalc" is desirable but could prove tricky
    with packages in other repositories depending on the filename.
