Simplify run_cmd

sfc.lib.utils.run_cmd has a lot of unnecessary options which are never
used.
This patch simplifies this function and also fixes the returncode
checking (commands have terminate with errors on returncode != 0 not on
return code < 0)

Also change the return value on error to None instead of False
