fix(roadtrip): the alternatives list compared two routers' drive times

The ways of driving one leg come from OSRM, except the toll-free or
motorway-free offer beside them: the shipped OSRM hosts are built without
excludable road classes and answer exclude= with HTTP 400, so that one is
asked of the avoidance router instead.

Their figures were then read against each other. The quickest was elected
across both, which is what decides the road drawn as the one being driven,
and every other road was labelled with how far behind that election it sat.
The two engines agree on the road to a tenth of a percent and not at all on
how fast it may be driven: over twelve European legs the per-leg time ran
from 14.7 % under OSRM's to 13.2 % over, with the sign following the region.
On a Spanish motorway leg that gap alone is enough to crown a toll-free
detour and call the motorway somebody is on the slow way round.

An offer now carries the engine that timed it. It takes no part in electing
the quickest, no difference is printed across the two, and the bar says where
the figure came from. Each route still reports its own time; only the
subtraction is refused. An instance running its own OSRM through the MLD
pipeline answers exclude itself, so there both figures are one engine's and
the comparison works exactly as before.
