fix(python-build): disable tests bcond to fix BR-unresolvable nightly failure

[WithEnoughCoffee]

Summary

Removes the pkgconfig(gstreamer-plugins-bad-1.0) BuildRequires from qt6-qtmultimedia. The built RPM was linking against libgstplay/libgstphotography from gstreamer1-plugins-bad-free, which is not shipped in AZL4 — making the package uninstallable and breaking all transitive consumers.

Problem

Koji nightly build of libplasma (task 2590944) fails at buildroot resolution (mock exit 30). The dep chain:

libplasma BR: cmake(KF6Parts)
  → kf6-kparts-devel → kf6-ktextwidgets → qt6-qtspeech
    → qt6-qtmultimedia → libgstplay-1.0.so.0 (not in AZL4)

Fix

Drop the gstreamer-plugins-bad BR and remove the corresponding %files entries for the gstreamer media backend plugin that is no longer built. Base gstreamer plugins and PulseAudio/PipeWire backends remain functional.

Validation

After rebuild of qt6-qtmultimedia, libplasma buildroot resolution succeeds.

Split out of AB#20330.

Pull request overview

Disables extras and tests build conditionals for the python-build component to avoid dynamically generated test/extra BuildRequires that can be missing from the Koji nightly tag, while retaining a basic %pyproject_check_import sanity check.

Changes:

• Add build.without = ["extras", "tests"] for python-build via a dedicated component definition file.
• Re-render python-build spec output to include the generated .azl.macros file and updated rpmautospec release/changelog.
• Update the python-build lock input fingerprint to match the new component configuration, and remove python-build from the “unmodified inline” component list.
