[Bug 1063770] [NEW] cloud lxc template leaves half-written files if interrupted

[Sidnei da Silva]

Public bug reported:

Happened two times already for me, once on a network glitch (where the
wget failed) and once where it never finished so I had to kill wget.

Eg:

drwx------ 2 root root      4096 Oct  8 10:28 tmp.jFQHxoBsm0
-rw-r--r-- 1 root root 179044352 Oct  8 01:02 ubuntu-12.04-server-cloudimg-amd64-root.tar.gz
-rw-r--r-- 1 root root   1556480 Oct  8 10:28 ubuntu-12.04-server-cloudimg-amd64.tar.gz

Doesn't seem like the script can recover from that situation, it just
tries to extract the incomplete tarball and fails.
