Without this change, e.g. 0.5.20 would not get --extra-clean, while it should.
Granted, the new test is buggy too, e.g. 0.7.1 will get --extra-clean,
while it should not. Will report that to Redmine.
duplicity >=0.6.20 now correctly removes useless signature files and
therefore the cache directory doesn't grow infinitely any more. Using
--extra-clean removes all signatures except from the last chain and so
renders older chains unusable, don't use it by default any more.

A fix for debian #677410 on commit 29dcdbae introduces a new issue on wheezy
machines where some rsync_options gets out of the rsync command quotes when
invoked by su.
As reported, running backupninja through `bash -x` shows that the `--delete`
option from the rsync command is not included in the single quote for the `su
-c` command:
nice -n 0 su -c '/usr/bin/rsync -av' --delete '--recursive
--delete-excluded //home/ /tmp/test//home//'
This patch attempt to solve that issue by using the intermediary variable
$command.
previously the code was modeled off of the partition backup methodology, this resulted in the code only attempting to detect luks on actual devices, and not on partitions. The code would step through every disk on the system (sda, sdb, etc.) and do a 'cryptsetup isLuks' on that device, and then based on that output save the luks header for any device that had one. Unfortunately, in many cases, luks headers are found on the partitions of those disks. So we were failing to detect any luks partitions and thus failing to backup their luks headers.
this commit changes that, it now will look for luks headers on the devices themselves (for cases where a full disk is used without partitions), and on any partitions that are detected
When --exclude 'something' is passed directly to rsync without going through
a shell, rsync tries to match a file whose name contains single quotes, which is
definitely not what we want it to do: exclude arguments protected with single
quotes are meant to be passed to a shell.
