Update env_logger to 0.5.4

It looks like this cuts down on the number of dependencies in env_logger and
notably cuts out a difference between a shared dependency of rls/cargo. My goal
here is to ensure that when we compile the RLS/Cargo on CI we only compile Cargo
once, and this is one step towards that!
