coverage: Add a script to generate directories per board.
This script reads the latest relevant build per board and then reads the
output of the GetDepGraph step. It then reads all the installed files
and outputs the directories under platform and platform2 that are being
installed on each board. Later, this will output a file that will be
used in zero coverage calculations. This is meant to be run manually
until zero coverage can do this automatically.
Output from the script - http://go/paste/6585903727247360
