Add back missing `tidy_checks`, since `tidy_checks_as_errors` isn't enough

I unfortunately missed in the original testing that
`tidy_checks_as_errors` isn't sufficient by itself. Instead we need to
have both places with the same variables. A future change will make
Soong expand `tidy_checks_as_errors` into both locations appropriately.
