Use python 3 for release tools

The release tools have already been updated in prior cls to
support python 3. To test this, I added code to print the script
name to a temp file at the beginning of every script, and then
ran various builds, ensuring that the scripts were run afterwards.

The builds run:
m brillo_update_payload checkvintf minigzip lz4 toybox unpack_bootimg deapexer (needed for releasetools_test)
m (as both sdk_phone_x86_64 and beagle_x15)
m target-files-package (as both sdk_phone_x86_64 and beagle_x15)
m releasetools_test && out/host/linux-x86/nativetest64/releasetools_test/releasetools_test (25 errors with and without python3)
m check_target_files_signatures apksigner target-files-package && out/host/linux-x86/bin/check_target_files_signatures out/target/product/emulator_x86_64/obj/PACKAGING/target_files_intermediates/sdk_phone_x86_64-target_files-eng.colefaust.zip
m dist
As aosp_cf_x86_64_phone: m dist && sign_target_files_apks  out/dist/aosp_cf_x86_64_phone-target_files-eng.$USER.zip /tmp/signed_target_files.zip && validate_target_files /tmp/signed_target_files.zip

This hit all the scripts except for make_recovery_patch,
merge_builds, and ota_package_parser.

I couldn't find anything that uses merge_builds, so it must
only be run manually.

make_recovery_patch and ota_package_parser are only run if
TARGET_OTA_ALLOW_NON_AB is true (among other things), which
is not the case for any product in aosp.

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For an outdated reference on Android.mk files, see build-system.html.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