[OE-core] [PATCH V2 1/1] runqemu: do not check return code of tput

[Chen Qi]

The subprocess.run was replaced by subprocess.check_call because
of compatibility support down to python 3.4. But we really don't
care about whether that command succeeds. Some user reports that
in some tmux environment, this command fails and gives some
unpleasant traceback output. So we use 'call' instead of 'check_call'
to avoid such problem.
