Use unified libtool version for all our libraries

- Our libraries are in reality so interdependent that its not even
  possible to use them independently of others, so having them
  all follow sort of independent versioning information just doesn't
  make any sense and is a PITA everytime I need to touch the data.
- This causes librpmsign soname bump with no good reason so its
  probably "evil" and all ... so sue me, its not as if anybody
  is actually using this library outside rpm itself.
