Move includes/DerivedConstants.h and includes/GHCConstants.h into dist dirs

When they existed, they were getting included in the includes_H_FILES
variable (as it uses wildcard to find all header files). But the
.depends files for the programs that generate the headers depend on
$(includes_H_FILES), so the .depends files looked out-of-date once the
headers had been created. This caused unnecessary make reinvocations.

So now we put them in dist* directories, where they ought to be anyway.
