Allow version 9 toolchains for EXPERIMENTAL_USE_OPENJDK9

By default, the Android build enforces an OpenJDK 8 toolchain,
whose name contains the strings "openjdk" and "1.8".

After this CL, the check can be changed to enforce a toolchain
name starting with "9" and without the need for "openjdk" having
to occur in the name.

This experimental new check can be enabled by running:
  export EXPERIMENTAL_USE_OPENJDK9=true
To switch back to the standard check, run:
  unset EXPERIMENTAL_USE_OPENJDK9

Test: make ANDROID_COMPILE_WITH_JACK=false checkbuild tests \
      && make checkbuild tests
      (with OpenJDK 8u45 toolchain on the PATH)
Test: make EXPERIMENTAL_USE_OPENJDK9=true \
      ANDROID_COMPILE_WITH_JACK=false checkbuild
      (with jdk 9-ea+170 toolchain on the PATH)
