Note that Platform.java is already on the boot library path for jtreg
and moving it to a separate class would need another entry here (in
TEST.ROOT):

requires.extraPropDefns.bootlibs = ../lib/sun ../lib/jdk/test/lib/Platform.java

The reason I've moved it to Platform for JDK-8227642 was that
VMProps.java previously hard-coded the docker command (it needs to use
the property value instead).

This seems work for little gain. Note that the intention is to change
"Docker" and DOCKER_COMMAND to something more neutral, like Container
or ContainerEngine. In light of that, Platform.ContainerEngine.COMMAND
makes sense to me.

Could I perhaps convince you to accept this version?
