Support older limesuite versions e.g. what's available on Raspbian Buster. 

Unfortunately limesuite doesn't seem to provide an API identifier, so
we can't detect whether LMS_PATH_AUTO is supported or not. Change the
fallback to LMS_PATH_LNAW, since that appears to work on both mini
and full-fat limesdrs.
