Bug#784368: fsck.btrfs is still in /bin, not /sbin

[Daniel Kahn Gillmor <dkg@fifthhorseman.net>]

https://bugs.debian.org/784368 shows that initramfs-tools is looking for
/sbin/fsck.btrfs, but btrfs-tools ships it in /bin/.

Ben Hutchings suggested back in May that btrfs-tools was going to put
fsck.btrfs back into /sbin in the "next version", though i can't tell
from the bug log which version that was, but 4.1.2-1 came out in August.

Maybe we could add the following line to debian/btrfs-tools.links:

bin/fsck.btrfs sbin/fsck.btrfs
