Show target information when running kirk instead of host

When LTX is selected and LTX runs in VM wrong host information is displayed, it's the host the kirk runs on. What we need to do instead is to collect the host info by running commands via LTX.

I guess that this is actually misinterpretation, I noticed that it says "Host info" and includes link to the kirk logfile so it probably shows correct albeit useless info. If we run over ssh or ltx the host CPU is as irrelevant as it could be since we are only using that to run kirk to schedule tests. All that we need to print in the host info is the temp directory and possibly python version.
