Control: affects -1 src:showtime

I can build the showtime package successfully in Trixie. If I then
install the dh-python 6.20250414 packages in my sbuild with unshare,
the build fails. The showtime packaging is very simple.

Hi Jeremy (2025.04.19_19:40:44_+0000)

I agree that that's a regression, but it doesn't seem to be a serious
one. It's trying to edit a file, and for some reason that file wasn't writeable.

I can make it force permissions to be writeable before fixing the file,
and close this bug, but I really think that the problem is the file's permissions.
