Support system_dlkm in GSI

From Android 13, all devices must include a system_dlkm partition.
The patch enables system_dlkm on all GSI targets to support the devices
with system_dlkm partition, and be compatible with old devices
without a system_dlkm partition.

With patch, there is no /system/system_dlkm, and add a symlink
/system/lib/modules -> /system_dlkm/lib/modules

Bug: 256984997
Test: make gsi_arm64-user and aosp_arm64-user; check system folder

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For an outdated reference on Android.mk files, see build-system.html.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