Subject: [PATCH] Revert adding .git-revision unconditionally

This reverts commit 1e534e234b0a92bf06361fa41b7ac8691fdbc769.

We already should have a .git directory if it is managed via Git,
otherwise there is no way to get the Git revision if neither
.git-revision or .git is present.

But having .git-revision _and_ .git present seems very much redundant to
me.
