state: report spaces in the state list parsing

This patch adds better error reporting when the user inserts a space
between two states with the --state option.

iptables -I INPUT -m state ESTABLISHED, RELATED
                                       ^
				  mind the space

results in:

iptables v1.4.2-rc1: Bad state `'
Try `iptables -h' or 'iptables --help' for more information.

Now this returns:

iptables v1.4.2-rc1: `--state' requires a list of states with no
spaces, e.g. ESTABLISHED,RELATED

This patch also applies to libxt_conntrack which has a copy of the
function.
