Disable the AppOp Restriction for IpSec Tunnels

This CL temporarily removes the AppOp restriction
that disallows creation of IpSec tunnels due to
the lack of the appropriate AppOp in AOSP/master.
When the relevant framework merges out to master,
this CL should be reverted.

Manually merging this due to skipping a merge
conflict at 9fe9ec18c1

Bug: none
Test: compilation
