ec: Improve coverage report.
Exclude the test directories from ec coverage report.
Include the test name into the coverage data.
Show the test name details in the coverage report.
Build several boards with coverage enabled, and use that to make sure
all used files are in the coverage report.
This lowers the coverage to 38.4% which seems much more realistic than
the old value.
