RFR: 8295176: some langtools test pollutes source tree [v2]

[Jan Lahoda]

> The `ReleaseOptionThroughAPI.java` test compiles another test source, `ReleaseOption.java`. But it does not specify the output directory, so javac generates the classfile next to the source files into the source directory, causing trouble.
> 
> The proposed fix is to add `-d .` to the test, so that the classfile is not generated into the working directory.
