Outdated /etc/os-release file

[Pino Toscano]

The /etc/os-release file provided in CirrOS images is outdated, and referring to generic buildroot.
Considering that the purpose of os-release [1] is to identify the OS, the current content shipped in CirrOS images gives wrong information about it:

$ wget http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img
[...]
$ virt-cat -a /tmp/cirros-0.3.4-x86_64-disk.img /etc/cirros/version
0.3.4
$ virt-cat -a /tmp/cirros-0.3.4-x86_64-disk.img /etc/os-release
NAME=Buildroot
VERSION=2012.05
ID=buildroot
VERSION_ID=2012.05
PRETTY_NAME="Buildroot 2012.05"

(virt-cat from libguestfs is used to inspect the image)
