Public bug reported:

I needed to patch a few places in distros/arch.py to get cloud-init to
work on Arch. This is with an OpenNebula-based cloud, but that shouldn't
matter. In /etc/cloud/cloud.cfg I obviously used "arch" for system_info
-> distro.

I checked against current trunk version of distros/arch.py. There's 3
issues in arch.py that this patch fixes (in order of appearance in the
patch):

1. The loopback device is returned as an entry by
net_util.translate_network(), leading to it gettingprocessed to
configure settings like IP address, netmask, etc, but these aren't
available and leads to an exception. I simply removed the "lo" entry
from the dictionary.

2. The netctl command expects its profile files to be named
/etc/netctl/<iface>. The code in arch.py leaves out the last separator,
leading to files like /etc/netctleth0, which doesn't work

3. The function convert_resolv_conf() can't possibly work, as it tries
to iterate over the "list" type instead of the "settings" list.
