Revert^2 "Fix CompilerDriver's handling of boot image extension."

This reverts commit 96d8585ebb9e21fc27a59ddd4173ca62ad93c194.

Fixed verification from oat files when compiling a boot
image extension. Normal verification can fail if the
primary boot image is quickened.

Test: `art/tools/buildbot-build.sh --target` with master-art manifest
Test: m test-art-host-gtest
