Fix bug in module deprecation from 0.9.0 release (#527)

With the bug, `using StaticArrays.FixedSizeArrays` did not result in a
module name `FixedSizeArrays` in the current namespace, thus breaking
explicitly qualified name lookups like `FixedSizeArrays.Vec(1,2)`.

Provide a binding for this explicitly.
