obs: lib.args: store argparse result here

Prepare to add more arguments to the OBS scripts, so they can be used
for building the wireshark package in its own OBS project.

It was not so clear to me when writing this initially, but with more and
more arguments getting added: it's not very maintainable to pass each
variable from the argparse result several functions down to where it
gets used... so unfortunately this means the code needs to be refactored
to just use libs.args in the few lines of code where the arguments
actually get used.

This patch adds lib.args, and the next patches refactor existing code to
use it instead of passing parameters, where it makes sense. After that
follow the patches related to adding the wireshark package.
