This is not a library, so there's no reason for them to be `pub`.
Without doing this, compiling the test crates causes private dep
lint errors:

error: could not compile `std` (test "create_dir_all_bare") due to 2 previous errors
This happens because Cargo passes `--extern 'priv:std=...` when
compiling the test crate.
I'm not sure if these warnings are desirable or not. They seem correct
in a very pedantic way (the dependency on `std` is not marked public,
since it's implicit), but also pointless (the test crate is not an API,
so who cares what it does).
Moving `create_dir_all` out of `ui-fulldeps` is complicated by the fact it sets the current directory. This means it can't be a unit test. Instead, move it to its own integration test.
