Mock umount all patch

[Alan Franzoni]

Hello,
I'm sorry needing to push this but I think it's really useful and I
don't want it getting lost for no apparent reason.

There was this feature for which I created a ticket:

https://fedorahosted.org/mock/ticket/4

It was then discussed on the ml:

And it seemed all-right back then.

But still it was not applied.

I pushed it forward once more recently, in order to cope with some
recent modifications to the trunk:

Could it be applied now? Otherwise, if there's any pending issue,
please tell me and I'll fix it.

Thank you,
