pySim-shell: Create/delete RuntimeLchan objects on open/close of channel

We already have the open channel and close_channel commands in
pySim-shell. They are sent to the card and acknowledged, respectively.

We also already do have code that can track multiple different logical
channels (the rs.lchan array).  However, this is currently only used by
pySim-trace, and not by pySim-shell.  Let's change that.
