sepolicy: Define and allow map permission for vendor dir

This patch tries to provide similar functionality as the previous
change made here:
https://android-review.googlesource.com/#/c/platform/system/sepolicy/+/432339/



Only, making sure we add the same map permissions for the vendor
directory.
