WiX: correct Dispatch.swiftmodule spelling, x86 builds

Correct the case on the swiftmodule directory name which would prevent
Swift from finding the correct swiftmodule.  We would fail to realize
this installation issue on Windows without a clean installation as the
filesystem is case insensitive.

The x86 manifest missed the directory path for the swiftmodule for
Dispatch.  Correct that while fixing the dispatch swiftmodule.
