Sepolicy: allow otapreopt_chroot to mount vendor

Browse source 
(cherry picked from commit ec4b9d6705)

Vendor apps are usually not preopted, so A/B dexopt should pick
them up. update_engine is not mounting the vendor partition, so
let otapreopt_chroot do the work.

This change gives otapreopt_chroot permission to mount /vendor
into the chroot environment.
