fix(webkitgtk): drop gstreamer-plugins-bad BR, disable MSE/EME

gstreamer1-plugins-bad-free is not shipped in AZL, so the hard
BuildRequires on pkgconfig(gstreamer-plugins-bad-1.0) caused dnf
builddep to fail during chroot init. Remove the BR via overlay and
pass -DENABLE_MEDIA_SOURCE=OFF / -DENABLE_ENCRYPTED_MEDIA=OFF to
both cmake invocations (GTK4 and GTK3) so WebKitGTK does not try to
consume gst-plugins-bad headers at configure time. This disables
MSE and EME backends in AZL's WebKitGTK build.

+# Extensions (EME) backends; remove the BR and disable both features at
