For the langtools shell tests, the tests already declare variables for 
$java, $javac, $jar and $jimage, so it is no big deal to update the 
definitions to use ${EXE_SUFFIX}

It seems like a good precedent for retaining unobtrusive clarity in 
shell tests, to use variables for the paths for the JDK tools.
