[utils] Add a '--unified-report' option to the code coverage prep script 

In --unified-report mode, a single coverage report is prepared for all
specified binaries and written to *report_dir*. This mode is compatible
with all existing script options, including the --restrict mode which is
used to limit coverage reporting to certain files or directories.

This should not break any existing users of the script.
