ddclient: T5792: Use Debian build from Trixie

As part of "T5792: Upgrade to ddclient 3.11.2" in commit 368b89e,
ddclient was built using build system from Debian Salsa and source code
from upstream GitHub.

This was subsequently modified in commit 7f7030d to use both build
system and source code from Debian Salsa.

Now that Debian finally has ddclient 3.11.2 release, we can use the
release tag to build the package.
