Before this fix, osmo-remsim-client-st2 contains both the -st2 and the
-shell binary, creating conflicts when both osmo-remsim-client-st2
and osmo-remsim-client-shell are installed, as both ship the -shell
binary.

The -shell client has no dependency to libosmo-simtrace2, so it makes
sense to package it separately.
