Simplify soong_java_prebuilt.mk and soong_app_prebuilt.mk

Simplify importing Soong modules into Make by always copying
LOCAL_PREBUILT_MODULE_FILE to LOCAL_BUILT_MODULE, which lets
Soong pick the final output file instead of trying to figure
out which of the various intermediate files should be the
output file.

Also fixes an issue where hostdex modules could attempt to
copy to both $(common_javalib.jar) and $(LOCAL_BUILT_MODULE),
which are the same file for host java modules.

Test: set compile_dex:true on core.platform.api.stubs. no warnings
      of target overriding
Test: m checkbuild

Android Make Build System

This is the Makefile-based portion of the Android Build System.

For documentation on how to run a build, see Usage.txt

For a list of behavioral changes useful for Android.mk writers see Changes.md

For an outdated reference on Android.mk files, see build-system.html. Our Android.mk files look similar, but are entirely different from the Android.mk files used by the NDK build system. When searching for documentation elsewhere, ensure that it is for the platform build system -- most are not.

This Makefile-based system is in the process of being replaced with Soong, a new build system written in Go. During the transition, all of these makefiles are read by Kati, and generate a ninja file instead of being executed directly. That's combined with a ninja file read by Soong so that the build graph of the two systems can be combined and run as one.
