Fixes flyspray 1100 for me.

- 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
  commands (on second thought I am not sure whether this is really
  needed).

Fixes flyspray 1112.
Please check whether flyspray 1100 is also resolved.

After review this should definitely be merged into the release branch.

* while traversing the tree, the modules now have a dedicated state:
   MAIN=one of the selected modules
   DEPS=added due to dependencies
   SUGS=added due to suggestions

Hopefully the last fix concerning flyspray 895.

Maybe the release managers could merge this to the release as they 
opted for simply reverting my changes instead of just reopening the bug. The latter would have caused less work.

Fixes flyspray #895

The problems was that INSTMODULE was overwritten in find_modules_in_path.
For MODULES (the non-installed ones) this was not a problems since new modules
were appended already in find_module.
