[PATCH] Add checks for iptables and iproute2 (Was Re: Coral with Xen)

[Anthony Liguori <anthony@codemonkey.ws>]

The following two scripts add checks for iptables and iproute2 during 
install.

Not all distributions include these by default.  I know this was a 
source of problems (with Gentoo) for me as the network scripts used by 
Xend silently fail if these commands aren't available.

It could be that Coral does not include one of these two packages by 
default.
