mmrnmhrm: Change to btrfs-only filesystem layout.

So, this was a big adventure during the last days, because as you might have
guessed from my older configuration this was a single-disk system. And that
single disk failed, so I had to do data recovery instead of actual useful things
in upstream NixOS. Fortunately I could recover everything, so nothing is lost...
just a bit hard to find :-D

Anyway, the new filesystem layout is now without LUKS and LVM, as I really want
to have the flexibility to change striping/raid behaviour per file and possibly
encryption as well someday.

Well, as you might have noticed from the previous commit: ecryptfs is now built
into the kernel and is currently my workaround for encryption until btrfs
finally gets native crypto support.
