gradle: convert gradle-wrapper.properties into a real generated file

Let's handle gradle-wrapper.properties the same way as gradle-wrapper.jar:
by downloading it during invocations of gradlew if it's not already there.

I also put gradle/wrapper into .gitignore since it is only expected to
contain generated files.

Finally, I added an ASL2 header to gradlew and linked to it from Kudu's
central license file.
