Pass signing_args to apexer to repack apex

In the build signing environment, we don't necessary have access to the
physical private key. And we work around it by passing an extra
signing_helper to the avbtool instead of a private key. Since we need
to perform signing to add the hashtree footer when rebuilding the apex
image. We should propogate the signing_helper to apexer and eventually
to avbtool.

Bug: 148627666
Test: unit tests pass. Smoke test by pass a public key to apexer and
hardcode the private key in signing helper script.

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For an outdated reference on Android.mk files, see build-system.html.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