Debian: Improvements to dependencies
Debian: Improvements to dependencies

* Added "ccache" to suggests of the package, it is really useful to
  speed Nuitka up when compiling repeatedly.
* As found by Yaroslav Halchenko, the "python-dev" dependency was missing
  and the build dependencies can use the -"all" variants for better
  coverage of the testing.
* While at it, I noticed that g++-4.5 was not allowed as a runtime
  dependency, breaking older Ubuntu packages. And for "scons" the
  build only wanted "2.0.0" where as for runtime, "2.0.1" was still
  needed. That breaks oldest Ubuntus as well.
