No new tests have been added yet, but existing tests in
gnovm/tests/files are now executed in the context of the package which
contains the relevant interpreter virtual machine and parser code. We
have now a better baseline to measure and complete the code coverage.

This represents more than 800 tests, which takes 10s on my macbook air
m1. Those tests are actually run twice, as I haven't yet removed the
original execution from gnovm/tests.

The testing code is substantially simplified compared to its counterpart
in gnovm/tests, but has not yet been deduplicated. This will be done in
further commits.
