(urgent) RFR: JDK-8201222: JDK-8199539 broke the OpenJDK build

> The fix in JDK-8199539 works fine for OracleJDK builds but broke the
> OpenJDK build. The problem is that I used CUSTOM_ROOT as the SRC dir for

> The idea was that I didn't care about the source dir but just wanted

> reworked this to instead loop over the files and call SetupCopyFiles
> once for each file to be copied instead.

Looks good.
