Correct FixIOException's @since annotation retroactively
Summary:
In D4113, a `FixIOException` data type was added with a
`@since TODO` annotation, but it seems that `TODO` made it out into
`base-4.11` itself. I've (retroactively) fixed this and added an
entry to the `base-4.11` entry in the `changelog`.
