osmo_pfcp_tool: make usable again

Browse Source 
Some things in osmo-upf and libosmo-pfcp have changed without accounting
for that in osmo-pfcp-tool. (This tool is not that important, forgive me
for submitting various changes in one patch.)

Properly represent all of {access,core} x {local,remote} GTP F-TEIDs in
the internal osmo-pfcp-tool state.

Adjust and clarify osmo-pfcp-tool script commands.

Adjust the osmo-pfcp-tool scripts in contrib so that they work again.
