openh264 is redundant for the editor — H.264 decodes use FFmpeg's native
decoder and H.264 encodes go through libx264 — but the probe still
enabled it wherever a pkg-config file existed, and FFmpeg links its
external codec libraries dynamically. The editor therefore required the
distributor's libopenh264 soname package (Debian's libopenh264-7, the
openKylin container's libopenh264-8 while the openKylin livecd only
ships -7), a dependency the editor never exercises. Drop the probe and
the -dev package from install-deps.sh on every platform.
