Scope coverage report generation to nova module.

Coverage report generation was not using --include filters.
This resulted in generating a report that included all external
dependencies. Some of these may include problematic characters for
utf8 decoding. In the odd case this was found, coverage would fail
with a UnicodeDecodeError.

Fixes bug #987077.
