Select log version 0.4

`0.*` selects is essentially the same as `*` since `0.1`, `0.2`, etc. do
not have to have a compatible API. Every other crate using logging
depends on `0.4`. Do the same here for consistency.

Using `0.*` is also incompatible with `-Z minimal-versions` because it
selects `0.1` which does not compile with any post 1.0 rust compiler.
