Package incfusever is only here to prevent go src tools (like godep)
from thinking fuseversion is not a required package. Though we do not
actually use github.com/jbenet/go-fuse-version as a library, we
_may_ need its binary. We avoid it as much as possible as compiling
it _requires_ fuse headers. Users must be able to install go-ipfs
without also installing fuse.
