Make base image more thin

[ogarcia]

• Remove inetutils, iproute2 and iputils unnecessary packages.
• Delete man pages (have not sense in a container).

Sorry for first commit using rm to delete man pages. I have not noticed that wildcard are picking the list of files from outside of chroot. 😞

In the other hand, I'm investigate why fails pacman-key --populate archlinux. Seems that depends of iproute2 package, but I dont know why. 😮

Ok. I found the issue, seems that lsign-key process fail because gpg returns an error code if libusb is not installed.

Update: I file a bug in pacman -> https://bugs.archlinux.org/task/54271

Other unnecessary packages in the image include systemd, dbus, iptables and associated dependencies/libraries.

The bug is closed and the make works well. I think that this PR can be merged.

The most minimal setup can be found in the "minimal" branch. I am not sure about this though. We can go two different routes here:

• Provide an image that includes everything from the "base" group except those packages that do not make sense in a container
• Provide everything that is needed to successfully run pacman.

I tend to the latter. This would make using it in interactive mode harder but for just building images that would be fine. Any thoughts?
