Fix core-ojtests-hostdex compilation for -target 1.9

This make target includes ojluni/src/test/java/util/stream/{bootlib,boottest}
tests that are in libcore packages; this fails when compiling with a
javac that implements the module system (such as when
EXPERIMENTAL_USE_OPENJDK9=true).

After this CL, --patch-module=java.base=[...] is used to patch this
target's sources and classpath .jars into java.base at compile time.
No run-time change is currently needed because these tests are run
on dalvikvm (on host), which currently doesn't implement the OpenJDK 9
module system.
