Rewrite aurblup in Python

The AUR backend already uses several Python scripts, rewrite the aurblup
helper as well. This has several advantages:

* We can easily use the main configuration file without using any shell
  script wrappers.

* aurblup does not need to be recompiled on libalpm soname bumps.
