- Remove unnecessary path to control file (It was needed for building
  installed modules which we do not do any more
- Test for ../../pkgconfig/$modname.pc to decide whether a module is 
  installed or not. Fixes flyspray 1100.

  do exist, as they are actually one file for installed modules.)
- Only build modules that are not installed
- Store relative path of CONTROL file and use it during running

These leads to kind of weired variabable names (dune-common_DIR,
dune-common_LIBRARIES, etc.) but finds non-installes modules
easier. You just sets CMAKE_PREFIX_PATH to the directory containing
the modules.
