[OE-core] [PATCH] qemurunner: Drop error to a warning to improve user feedback

[Richard Purdie]

If a task shows an error, the full log is surpressed since bitbake assumes
the user has been shown what is wrong. In this code path that isn't the
case and its much more helpful to show the user the full error. Therefore
show a warning instead to aid usability.
