[PATCH] testbot/WineRunTask: Use a trampoline script to capture cmd errors.

[Francois Gouget]

This side-steps the console / redirection bug in the currently deployed
versions of TestAgentd.
This also side-steps cmd's command line parsing bug. When given
["cmd". "/c", "script.bat >Task.log"] TestAgent would build a command
line of the form '"cmd" "/c" "script.bat >Task.log"' which would lead
cmd to try to run '"script.bat >Task.log'. This would fail because of
the extraneous double quote. Note that cmd fails in the same way for
'cmd "/c" "script.bat >Task.log"'.
