Deb: Fix various shortcomings in the control file

- All build-depends should be in one place.
- Library packages should depend on their main package using strict version.
- Most packages should depend on the misc variable, so that debhelper
  can fill in it with various calculated dependencies automatically.
- All packages using dynamic libraries should depend on the shlibs variable
  to include shared libraries as dependencies automatically.
- Essential tools like bsdutils, grep and tar shall not be defined in vain.
