redhat: remove automatic git operations from automotive scripts

Bugzilla: INTERNAL
Upstream Status: RHEL only

The way the script was implemented it copies files that can affect the dist-git target like .gitignore file. There are other files being generated that don't need to be copied. This commit also implements a forced clean up into dist-git SOURCES/. This is a good reason to remove all the automatic operations from automotive scripts. Now, there is no automatic commits and sync's. Everything should be reviewed first and then pushed by the maintainer of the dist-git repository. Including, the update into the source-git.
