add check if salt-minion is running to base

for RT-8518, which asks for a way to detect
if salt-minion is running

adding this to base so _all_ hosts would get
the new check

using --ereg option and not just -C to avoid
the common issue where 2 processes are reported,
while 1 of them is the check seeing itself causing
a false positive
