Remove javac support in host dex rules.

Remove javac support in host dex rules.

- Remove javac support in host_dalvik_java_library.mk
- Simplify host_dalvik_static_java_library.mk by including
  host_dalvik_java_library.mk instead of host_java_library.mk.
- Take configure_local_jack out of host_java_library_common.mk because
  it's only needed by host dalvik java libraries.
