Update code coverage filtering

Replaces old LOCAL_EMMA_COVERAGE_FILTER by new variables:
- LOCAL_JACK_COVERAGE_INCLUDE_FILTER for included classes
- LOCAL_JACK_COVERAGE_EXCLUDE_FILTER for excluded classes
Both variables can contain a comma-separated list of class names,
where * and ? are accepted wildcard (like foo.?ar.*).

When code coverage is enabled, we will use these variables to
pass code coverage filters on the Jack command-line.
