mtf: Use vendor otatools for checking rc-files on vendor and odm

host_init_verifier is getting stricter and stricter with every new
android release. However when merging older (previous android version)
vendor target files, these checks become too strict.

Use host_init_verifier from vendor otatools on vendor and odm to not
enforce new requirement on VFR/GRF'ed partitions (vendor and odm).
