As "java" does, do not include the current directory to the classpath if
the explicit classpath is specified. This is more stable than always
adding the current directory, and users can easily add the ".:" to the
beginning of the explicit classpath themselves

The compiler behavior on test data in compiler/testData/cli is already tested
with CliTestGenerated, which is 4x faster and does not require to rebuild the
compiler jar with 'ant dist'. Leave only several simple tests to check that
'kotlinc', 'kotlinc-jvm' and 'kotlinc-js' scripts work
