JDK-8264744 - (fs) Use file cloning in Linux version of Files::copy method
Description
We noticed a startup and footprint regression on multiple applications starting since 20-b14. Cause appears to be JDK-8264744 which adds a call to load the nio library in the LinuxFileSystem <clinit>. 

I think refactoring the LinuxFileSystem::directCopy0 method (also recently introduced with JDK-8293121?) into LinuxNativeDispatcher would resolve this startup regression
