Follow symlink when creating symbols.zip

Due to the runtime APEX, the symbols directory now contains a symlink;
./apex/com.android.runtime -> com.android.runtime.debug (or .release).

Previously, this symlink itself was included in the symbols.zip file.
And this is causing problem to the online stack tool which does not
follow the symlink in the zip file. Instead of fixing the problem in the
stack tool side, this change let the packaging routine to follow the
symlink and copy the files behind the symlink as if they were under a
directory that isn't a symlink. (i.e.
./apex/com.android.runtime/bin/dex2oat is added)

Bug: 120846816
Test: m dist with marlin (flattened) and blueline (non-flattened)
examine symbols.zip file and check that unstripped shared libraries are
found under /apex/com.android.runtime directory

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For an outdated reference on Android.mk files, see build-system.html.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