An update that solves four vulnerabilities can now be installed.

## Description:

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  * Drop no longer valid translation-update-upstream BuildRequires and macro.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:
  * Add missing g-i annotations to `soup_address_get_sockaddr()` and
    `soup_socket_read_until()`.
  * Add missing `extern` when building on Windows.
  * Update libxml2 fallback for meson wrap.
  * Improvements when using libsoup with meson wraps.
