Refine lsdump_paths.txt dependencies

This commit moves $(LSDUMP_PATHS) from the prerequisite of
lsdump_paths.txt to the prerequisite of findlsdumps. This change makes
it possible to dump the list of lsdump files without actually building
all lsdump files.

Bug: 124829578
Test: make out/target/product/generic/lsdump_paths.txt
      # does not build the actual lsdump files
Test: make findlsdumps  # builds lsdump_paths.txt and all lsdump 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For an outdated reference on Android.mk files, see build-system.html.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.
