Remove make check invocation from legacy.run.sh

The legacy runner no longer uses make check. Ensure the legacy runner
script doesn't interact with that automake target in any way. The legacy
runner script remains available to execute the legacy runner, but there
is no out-of-the box support for running tests in parallel. Other tools
such as xargs can be utilized for that.
