ivtest: Run nested enum tests through vlog95

The br_gh1385a, br_gh1385b, and br_gh1385c JSON descriptors mark the vlog95
variants as compile errors. The enum typedefs are translated correctly, so the
compile error expectation causes the tests to fail when compilation succeeds.

Remove the stale overrides and run the translated tests through vlog95.

Fixes: 10349287a0 ("Add regression tests for enum typedefs in nested scopes")
