selftests: pmtu: maximum MTU for vti4 is 2^16-1-20
Since commit 82612de1c98e ("ip_tunnel: restore binding to ifaces with a
large mtu"), the maximum MTU for vti4 is based on IP_MAX_MTU instead of
the mysterious constant 0xFFF8. This makes this selftest fail.
Fixes: 82612de1c98e ("ip_tunnel: restore binding to ifaces with a large mtu")
