vm_map: Fix proxy object protection check
* If not making a copy, don't cap protection to the limit enforced
by the proxy, and only require read access. This fixes mapping
parts of read-only files MAP_ANON + PROT_READ|PROT_WRITE.
* Instead of silently capping protection, return KERN_PROTECTION_FAILURE
to the caller like the other vm_*() routines do.
