[PATCH] cygwin: Add cocom and patch to build prerequisites in FAQ

[Jon Turney]

Add patch, and make cocom unconditional in list of build prerequisites.

Even though the products of these tools are checked in, these are 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 is more recent than
the input.

Also drop a duplicate sentence about 'fetch sources from git'.
