init: allow vendor init to action on any vendor or odm property

Partial revert of "init: if vendor_init can read a property, let it be
a trigger too" (b35f827c).

We made a mistake when we allowed vendor init to action on any vendor
or odm property, since when a new SELinux label is created for a
vendor property, vendor_init does not automatically get read
permissions for it.

Recently, we tried to use read permissions instead of the built-in
list in init, but that broke due to the above mistaken.  Since we have
already launched with these permissions as is, we must restore them.

Test: no denials for vendor init actionable properties on crosshatch
