bts: create all components alive

This mitigates sporadic dynamic-testcase errors triggered by messages
being sent to components that have terminated before receiving them.

fixup: bts: create all components alive

Making the ConnHdlr and lapdm_CT components alive resulted in
massive regressions.  Specifically, trxcon started rejecting L1CTL
connections with the following message:

  L1CTL server cannot accept more than 1 connection(s)

Apparently, alive components do not close the L1CTL connection
automatially, unless the L1CTL port is unmap()ped from the system
explicitly.  Thus, testcases spawning multiple alive components
end up creating multiple L1CTL connections, which get rejected.

Let's revert those components that speak L1CTL back to normal
(non-alive), while keeping the emulation components alive.
