 ghc.mk: fix list for dll-split on GHCi-less builds

 To reproduce build failure it's enough to try
 to build GHC on amd64 with the following setup:

     $ cat mk/build.mk
     # for #9552
     GhcWithInterpreter = NO

 It gives:

     Reachable modules from DynFlags out of date
     Please fix compiler/ghc.mk, or building DLLs on Windows may break
 (#7780)
     Redundant modules: Bitmap BlockId ... <list of 42 modules>
     <make error>

 dll-split among other things makes sure
 all mentioned modules are used by DynFlags.
 '#ifdef GHCI' keeps is from happening.

 Patch moves those 42 modules under
 'GhcWithInterpreter' guard.

 Fixes Issue #9552
