Allows using mkfs.btrfs inside the initrd. Symlinking to btrfs does not work like it does with btrfsck/fsck.btrfs.

Shouldn't this be conditional on wanting to run mkfs from initrd?

Maybe. I just submitted this because I thought it might be useful, but I can also close the PR if this change is not desirable (e.g. due to larger initrd size).

Having an option to do this might be useful indeed, but I don't think we want to increase initrd size when the tool won't be used.

I decided to switch to boot.initrd.systemd, so I'll have no use for this even myself.
