This CL pins the following make targets to java_version 1.8,
which is currently the default:
framework-protos
repackaged.android.test.base
repackaged.android.test.mock
repackaged.android.test.runner
For consistency, their dependencies,
android.test.base
android.test.mock
android.test.runner
which contain .java source files, are also pinned to 1.8.
This is so that the two steps:
a) update jarjar to support v53 class files
b) support -target 1.9 in the rest of the toolchain
can be completed in any order, in future CLs. Before this CL,
they would have needed to be completed in order a), b).

Test: EXPERIMENTAL_USE_OPENJDK9=true USE_R8=true make checkbuild docs
(in a client where CL http://r.android.com/596874 was reverted)
