Batch files no longer swallow exit codes

Usually scripts like scala.bat and scalac.bat correctly propagate
exit codes from underlying Java invocations. However, if you run these
scripts as follows: "cmd /c scala ...", then errorlevel gets swallowed.
This simple patch fixes the aforementioned problem.

Fixes SI-5295, no review.
