Critical Update for Debian 11: DLA-4122-1 Addresses libbssolv-perl Bug

This fixes a bug that prevents the Open Build Service backend from working
correctly. In particular, the Download on Demand feature is unable
to process woff-tools package from Debian, and ends up deleting the .deb
file immediately after downloading it.

See https://github.com/openSUSE/perl-BSSolv/pull/17 for more details
on this bug upstream.

This bug has also been fixed in Debian 12 bookworm and newer.

No other software is known to be affected by this issue.

For Debian 11 bullseye, this problem has been fixed in version
0.17-3+deb11u1.

We recommend that you upgrade your libbssolv-perl packages.
