BTS_Tests: exec TC_sacch_chan_act_ho_{sync,async} on g_AllChanTypes[]

Currently we execute both test cases on *all* available dedicated
channels from g_AllChannels[].  Given that SACCH is slow, and in
some cases we intentionally wait for a timeout of 3.0 seconds to
expire, the overall execution time is quite long.  We have a risk
of the test execution being aborted due to the guard timeout.

I agree that using g_AllChannels[] makes sense for TC_ho_rach, which
tests handover RACH detection.  There we want to be sure that detection
works on all slots of all DCCH types (especially when running a setup
with real MS/BTS hardware).

But for both TC_sacch_chan_act_ho_{sync,async} it's enough to run
on different channel types (see g_AllChanTypes[]), because what
we actually want to test is the Downlink SACCH operation.
