libdispatch: Avoid submodules for headers that should not be included

libdispatch has an umbrella header, dispatch.h, that should be used for
including all of the other headers.  This is enforced via
__DISPATCH_INDIRECT__.

Since it isn't legal to include one of the other headers on their own,
it isn't logical to have submodules for them.  Moreover, submodules
*should* have local visibility (be unaware of the context they're
included from); meaning that __DISPATCH_INDIRECT__ will never be
defined.

Logically, all of the headers are part of a single module/interface.
