mtreplay: print replay subprocess stderr on error
In touch tests, if the replay subprocess returns an error it's helpful
to know the error code and the contents of standard error for that
process.
BUG=none
TEST=run a touch test that causes a replay error, check stderr is
displayed. (I checked with the zgb/1f_click_resting_thumb test.)
