Summary: This change adds a virtual `Truncate` method to `Env`, which truncates the named file to the specified size. At the moment, this is only supported for `MockEnv`, but other `Env's` could be extended to override the method too. This is the same approach that methods like `LinkFile` and `AreSameFile` have taken. This is useful for any user of the in-memory `Env`. The implementation's header is not exported, so before this change, it was impossible to access it's already existing `Truncate` method.
