This update for libsoup2 fixes the following issues:

* CVE-2026-12548: out-of-bounds read in multipart body parser due to an

integer truncation (bsc#1272196).

Changes for libsoup2:

* tld-test: update after changes in the public suffix list: "*.bd" is no

longer in the public suffix list so let's use ".jm" instead.

* Increase test timeout for all arches except x86_64 and run tests again

should they fail the first time, the testsuite is flaky.

* Increase test timeout on s390x. The http2-body-stream test can be slow and

sometimes times out in our builds.

* fix an intermittent test failure (glgo#GNOME/libsoup#399).

* Fix build with libxml2-2.12.0 and clang-17.

* Add upstream bug fixes:

* lib: Add g_task_set_source_tag() everywhere

* lib: Add names to various GSources

* Drop no longer valid translation-update-upstream BuildRequires and macro.

* Use ldconfig_scriptlets macro for post(un) handling.

* Update to version 2.74.3:
