Check for presence of btrfs before trying to use it
If btrfs is not present in the kernel we end up with strange output like
this:
Error creating disk image2014-06-10 16:00:40
[devel-system-x86_64-generic][my-raw-disk-image][rawdisk.write]Failure
to create disk image at /src/tmp/testdev.img
ERROR: Command failed: mount -o loop /src/tmp/testdev.img
/src/tmp/deployments/tmpQ7wXO1/tmp4lVDcu/tmpvHSzDE
mount: mounting /dev/loop0 on
/src/tmp/deployments/tmpQ7wXO1/tmp4lVDcu/tmpvHSzDE failed: Device or
resource busy
To avoid this confusing error, Morph should explicitly check first.
