cros_generate_update_payload: Import installed chromeos-common.sh.
Don't import chromeos-common.sh from platform2/installer, since it
might not be present in a minilayout.
Also stopped trying to import from /usr/lib/installer, since we never
install the script there in any environment I can find.
BUG=brillo:396
TEST=Built, build_image, network update a dut.
