Fix ota_from_target_files error in non-AB VF

For vendor freeze, vendor.img/odm.img is rebuilt and moved to
the merged target files dir in a special build flow:
https://android-review.googlesource.com/c/platform/build/+/1752968

But considering non-AB case, some more files are generated by
MakeRecoveryPatch() along with vendor.img, such as:
IMAGES/vendor.map
VENDOR/etc/recovery.img
VENDOR/bin/install-recovery.sh

They should be copied to the merged target files dir as well,
in order to pass the check in HasRecoveryPatch() and
GetSparseImage().
