Don't add private module headers for private modules when not needed

If a module has the NO_MODULE_HEADERS option, we should not add
the private module header paths to the BUILD_INTERFACE of private
modules.

This fixes building static non-prefix qtdeclarative builds on Linux,
where non-existent QtXcbQpa headers failed the qtdeclarative
generation step.
