Merge #17647: lcov: filter depends from coverage reports

f736f69 lcov: filter /usr/lib64 from coverage report (nijynot)
a5a705b lcov: filter depends from coverage report (nijynot)

Pull request description:

  If you build the binaries with the `depends` folder and then generate coverage reports with `make cov`, `depends` will be included in the coverage reports. Coverage of the dependencies are not that interesting and should be filtered.
