[PATCH] release/live: fix a Makefile dependency being missing in Nix shell

["Johannes Süllner" <johannes.suellner@mailbox.org>]

In commit a6d872ae, a Btrfs userdata partition was added to the live VM
that can be startet with `make run`. The Makefile creates this partition
and therefor requires `btrfs-progs`.

Fixes: a6d872a ("release/live: allow writes in "make run"")
