Make libdexlayoutd actually have art debug flags

Previously it didn't, this caused DCHECKs to not happen. Disabled
dex verifier for dexlayout since it fails for dex2oat_image_test
now that DCHECKs are actually run.

The failure is:
Check failed: output_dex_file != nullptr Failed to re-open output
file:Failure to verify dex file 'memory mapped file for
.../core-oj-hostdex.jar': Out-of-bounds end of data subsection:
4c56d1

Test: test-art-host
