hnbgw: initial_ue_empty_cr: use larger payload to trigger empty SCCP CR

osmo-hnbgw will deprecate the 'sccp cr max-payload-len' config option.
To still trigger the 130 byte limit that is now enforced in
libosmo-sigtran, enlarge the NAS PDU.

So far the limit set via VTY was 0 bytes, which will no longer happen in
osmo-hnbgw after I18dece84b33bbefce8617fbb0b2d79a7e5adb263.
