test: create and merge code coverage reports in integration tests

Browse source 
If -Db_coverage=true is used at build time, then ARTIFACT_DIRECTORY/TEST-XX-FOO.coverage-info
files are created with code coverage data, and run-integration-test.sh also
merges them into ARTIFACT_DIRECTORY/merged.coverage-info since the coveralls.io
helpers accept only a single file.
