BE flag logic for Origin needs improving

[DanyC97]

Writing it down before i forget ..
currently when BE flag is enabled we do the following:

• Jenkins job set the ORIGIN_VERSION to default value
  • default value is static and needs to be changed everytime upstream is being changed. This logic is a catch 22 since someone needs to always be ahead / up to date with upstream so we can get the job working (which runs every 3 h)
• we clone master origin branch
• we set ORIGIN_VERSION default value passed in in the origin.spec file
• tito builds the rpm with the modified rpm
• cbs is pushing the rpm however that fails - see here since the rpm is origin-3.10.0-0.alpha.0.el7.git.0.af33468.src.rpm but in the build.log we can see it detects a different OS_GIT_VERSION=v3.11.0-alpha.0+af33468-8 . That is because we passed something else [1]
