RFR: 7903550 - Broken backward compatibility in JCov build scripts

[Jiří Vaněk]

By using proper target name, 7903550is now fixed.
Custom path, or even custom name can be (again) provided via both -D runtime property or via build.proeprties.

Accidenatly, also CODETOOLS-7903551 was fixed.
7903551 - Move JCov dependencies into a sub-dir.
Now the libs are by default downloaded to the build/./lib This directoy canbe changed via deps.dir property, so now you can manage the whole folder with deps by one property if needed.
