Fork shadow for java9 support.

This is a prerequisite for updating ASM to ASM 6.0 so that we can
support java9. ASM 6.0 now has a java9 class file in its distribution
and our repackaging needs to be able to deal with it.

Once shadow is updated upstream we can remove this setup again.

Since this is a gradle plugin, we need to download this up front
in the same way that we download gradle itself. Therefore, once
this lands everyone needs to run ./tools/gradle.py at least
once to get the new dependency downloaded.
