Revert to once again use the legacy build system.

Tulsi breaks with the new build system in Xcode 10.2 (beta) since
it requires a codesigning identity to be present. If we disable codesigning,
then injected test frameworks are not signed properly since Xcode injects them
after running Tulsi's scripts.
