This update for osc, build, obs-service-set_version and obs-service-tar_scm adds enhancements to use cpio
archives in local builds.

The new versions of these tools are required to use the new obs_scm service in local builds with osc.
This makes builds more flexible and gives developers the ability to work in a local working copy of
their VCS system and build packages from the local checkout.
