coverage report file names are somewhat redundant

same for html and xml ; we shoud prefer a shorter form

[coverage_report-coverage_nano.html](https://openqa.opensuse.org/tests/5138848/file/coverage_report-coverage_nano.html)
[coverage_report-coverage_nano.xml](https://openqa.opensuse.org/tests/5138848/file/coverage_report-coverage_nano.xml)

`coverage_report-$BINARY` might be enough

Start by locating the code that generates the HTML and XML coverage reports, using the linked coverage_report-coverage_nano.html and coverage_report-coverage_nano.xml artifacts as examples. Check how the binary name is incorporated into each output filename; done means both formats use the shorter coverage_report-$BINARY form without breaking report generation.
