[Tails-testers] Dotfiles broken in 2.0

I'm writing here because I expect intrigeri to process a first batch of
reports by email, remove duplicates, etc. Tell me if I should instead
create Redmine tickets, but this will probably take me more time.

Dotfiles are broken in 2.0 as
/lib/live/mount/persistence/TailsData_unlocked doesn't exist and they
are pointing to it.

As a workaround, I'm doing right-now:

install -m 755 -d /lib/live/mount/persistence

install -m 755 -d /lib/live/mount/persistence/TailsData_unlocked

mount --bind /live/persistence/TailsData_unlocked
/lib/live/mount/persistence/TailsData_unlocked
