    util-linux: add rev utility package
    
    I found use for this in my scripts; I noticed that it is already
    compiled with util-linux - there just isn't package for it -
    let's package it then.
    
    Description:
    The rev utility copies the specified files to the standard output,
    reversing the order of characters in everyline.
