gtphub: simplify/fix: one TEI mapping per tunnel.

Because the sender is known, one unique TEI per tunnel suffices to map the TEIs
that the peers are sending to gtphub, instead of previously 4 (SGSN<->GGSN
interaction on User and Ctrl plane, where each had an own unique TEI).

Also, previously, a tunnel's endpoints should also have been checked against
each other for TEI reuse, not only against the endpoints of other tunnels. This
simplification fixes that problem for free.

Thus simplify TEI reuse detection and improve VTY show readability and
debugging.

Adjust log and VTY output for tunnels.
Adjust tests accordingly.
