dg.spec.rpkg: Reflect changes in Fedora's CMake macros

* Add docs to the package
* Do not set CMake buildtype as rpmbuild sets the default set of buildflags
* Fix some rpmlint errors and warnings
* Fix compatibility with openSUSE and Mageia

Closes: #327

 %description
-DG is a library containing various bits for program analysis. However, the main
-motivation of this library is program slicing. The library contains implementation
-of a pointer analysis, data dependence analysis, control dependence analysis,
-and an analysis of relations between values in LLVM bitcode. All of the analyses
-target LLVM bitcode, but most of them are written in a generic way, so they are
-not dependent on LLVM in particular.
