Add bootclasspath config to its own makefile

This is part of adding some devices/products suitable for unbundled
builds. An unbundled product does not need all the PRODUCT_PACKAGES
etc present in the normal hierarchy of products, but does need to know
which jars are on the bootclasspath.

Therefore, factor out the bootclasspath config from base_system.mk and
put it in its own makefile where it can be inherited by these unbundled
products.

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For an outdated reference on Android.mk files, see build-system.html.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.
