Ignore image checksum for ExtractOnly oat files
Oat files compiled with --compiler-filter=verify-at-runtime contain
no compiled code and therefore are independent of the boot image.
This patch stores an ExtractOnly flag in the oat header and skips
the image checksum test if the flag is set, rendering the oat file
up to date even after OTAs.
