Remove fs-verity build manifest for vendor/odm/product

The build manifest APKs are recently added because we thought it's nicer
for ART to support beyond system_ext for potential partner
customizations.  Jiyong pointed out that having system server JARs
outside of system and system_ext may be a Treble violation. As a result,
delete some of those files.
