Fix: utils: A workaround for the truncating issue (bsc#1205925)

When python program calling cibsecret with a small terminal width,
the command `ps -ef | grep '[p]acemaker-controld'` will return 1

>>> cmd = "ps -ef | grep '[p]acemaker-controld' >/dev/null"
>>> # When terminal width is small
>>> subprocess.call(cmd, shell=True)
1
>>> # When terminal is big enough
>>> subprocess.call(cmd, shell=True)
0

Set a large terminal width could be a workaround
