sugar-update-control: modifying files tracked by git

[sascha_silbe]

Filing against sugar as there is no Trac component for sugar-update-control yet.

Building/installing sugar-update-control modifies files that are tracked by git.
On a system where git isn't fully configured (i.e. anyone without commit rights) this will lead to sugar-jhbuild aborting with an error.
