Add missing #:modules argument for coverage-data->lcov.

Browse source 
The code coverage function `coverage-data->lcov` has a documented
`modules` argument, however that was missing from the source. I have
added it so when supplied it only converts the coverage data for the
supplied modules. If not supplied it defaults the old behavour of
including all the modules currently loaded.

* module/system/vm/coverage.scm (coverage-data->lcov): Add #:modules
parameter and honor it.
