[PATCH] dpkg: Configure sbuild for schroot

[Jan Kiszka]

From: Jan Kiszka <jan.k...@siemens.com>

This is what at least the trixie version of sbuild strongly recommends
and also what the forky version will require.

$chroot_mode is known to sbuild buster at least. It remains unclear when
$schroot was introduced, but it was very likely ignored before that. So
this changes is backward-compatible with older builders.

Tested with a local experimental kas-isar forky container.

Hmm, may clash with the unprivileged build series, though I didn't spot
yet where/how the sbuild mode is chosen there.

This should not be required (since [1]), as we select the chroot mode
when calling sbuild [2]. That's also compatible with the rootless
series where we just select unshare.

Indeed, I tested with an older Isar baseline and didn't notice this
switch while forward-porting. Let me double-check with 1.0-rc1 again if
the issue under forky is gone.

And it does work, of course - so please ignore this.
