bilby_pipe_gracedb ini file points to wrong distance marginalization lookup table for xphm

Looking at the recent online-PE runs that use the XPHM ROQ, it looks like distance-marginalization-lookup-table=/home/emfollow/.local/lib/python3.9/site-packages/bilby_pipe/data_files/4s_distance_marginalization_lookup.npz regardless of what the duration is for the analysis. I think this is because this function that sets the lookup-table to point to gets the duration from _get_default_duration, whereas choose_xphm_roq hard codes the analysis duration in a way that does not necessarily agree with the default duration function.

I think an easy fix would be to have _get_distance_lookup to take duration as an input.
