    cygwin: Add cocom and patch to build prerequisites in FAQ
    
    Add patch, and make cocom unconditional in list of build prerequisites.
    
    Even though the products of these tools are checked in, these tools are
    required when building in a fresh git checkout, presumably due to the
    order in which git creates the files resulting in timestamps which
    indicate that the output of rules using these tools are older than
    the inputs.
    
    Addresses: https://cygwin.com/pipermail/cygwin/2021-December/250124.html
    
    Also drop a duplicate sentence about 'fetch sources from git'.
