Simplify the coverage statistics summary
The script was parsing the output from `make lcov` to extract numbers and
calculate percentages. But everything including the percentages is already
present in the output of `make lcov`, just with a slightly different
presentation. So replace all this by a simple extraction of the relevant
lines from the output of `make lcov`.
This is more robust than the previous code, which relied on `tail -n4` to
extract relevant lines, which broke when `make lcov` started to emit one
extra line at the end.
