Bug#991822: src:wine: dh_auto_clean deletes unrelated files outside of package source

[Bálint Réczey <balint@balintreczey.hu>]

Package: src:wine
Severity: critical
Version: 5.0.3-3

Hi,

The following snippet in debian/rules wiped out every package source
next to wine and the wine source dir itself, too, because my $HOME is
stored in git:

...
override_dh_auto_clean:
        git clean -Xdf || true
...

It is not safe to assume that the package source is always a git directory.

Cheers,
Balint
