Add experimental option to use OpenJDK 11 toolchain.
With this change, setting the environment variable
EXPERIMENTAL_USE_OPENJDK11_TOOLCHAIN=true switches from the OpenJDK 9
toolchain to the OpenJDK 11 one (prebuilts/jdk/jdk11).
Since the version of the java.base module has to match the version of
the jlink tool which consumes it, the --module-version argument to the
jmod create call is also switched.
Test: make
Test: EXPERIMENTAL_USE_OPENJDK11_TOOLCHAIN make
