build: build deb/rpm independently on config/extensions in the host system

Reverts 5aac617a028d and replaces it with a more general solution.

- works for both rpm and deb
- sidesteps eventual problems with local extensions that have nothing to do with
  the build process (hg-git, for example, fails with version 4.4 because
  dedab036215d removed peerrepository, and hg-git still uses it as of 0.8.9)

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
