fs_config: fix fs_config_*_system targets

Content from fs_config designated for other partitions is leaking
into the system fs_config_* files.  Notably /vendor is showing up.

Rule expansion happens late, after all parsing.  This is the same in
make and kati.  build/make/tools/fs_config/Android.mk ends with
fs_config_generate_extra_partition_list :=, so by the time you get to
rule expansion the value is empty.

Added a PRIVATE_PARTITION_LIST variable to record the value of
fs_config_generate_extra_partition-list.

Test: inspect result of ${OUT}/product/*/system/etc/fs_config_files

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For an outdated reference on Android.mk files, see build-system.html.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