kbuild: do not overwrite .gitignore in output directory
Commit 3a51ff344204 ("kbuild: gitignore output directory") seemed to bother people who version-control output directories. Andre Przywara says: "Unfortunately this breaks my setup, because I keep a totally separate git repository in my build directories to track (various versions of) .config. So .gitignore there is carefully crafted to ignore most build artefacts, but not .config, for instance."
