config: runtime: tests: ltp: enable support for code coverage

When enabling code coverage support using in-kernel GCOV, we must first
reset coverage "recording" right before starting the test, then ensure
we pack and upload the resulting artifacts.

Those steps are executed by including the corresponding sub-templates
whenever the kernel has been built with GCOV support, IOW when the
`coverage` fragment is part of the build config.
