examples/mpls/net37: enable the demo (auto RSVP peers), record fingerprint

net37 is a 37-router RSVP-TE demo that never ran: it set **.LSR*.peers="" (no
peers), so RSVP had no HELLO neighbours and signaling failed with "not an RSVP
peer" -- which is exactly the manual-config drudgery the "auto" peer derivation
removes. Drop the empty peers setting so the routers use peers="auto"; the LSP is
now signaled and host1->host2 traffic flows over it.

Flip the fingerprint row from ERROR to PASS and record it. Use the same
ingredients as the sibling MPLS rows (tplx;~tNl;tyf) -- the stale ~tND ingredient
would force serialization of RSVP/MPLS packets, which have no serializer.
