Add dependency on android_tools in java_apk.gypi for all test apks.

This patch adds a dependency on entire android_tools target that contains
forwarder2 and md5sum to java_apk.gypi for all test apks, so that individual
test apk targets do not need to explicitly depend on the tools required to run
them.
