tests/run-tests.py: Unconditionally enable native tests if asked.

This commit lets the test runner enumerate and run native tests if the
feature check fails but native tests were explicitly requested from the
command line.

The old behaviour would disable native tests anyway if the feature check
failed, however this hid a bug in the x86 native emitter that would be
triggered even during the feature check.  That meant the test suite
would pass on x86 even with a broken emitter, as those tests would have
been skipped anyway.

Now, if the user asks for native code it will get native code out of the
runner no matter what.
