HLS/previews: rerun on the CPU when the GPU can't be used right now

A busy GPU (llama-swap holding the 3090) made ffmpeg's CUDA setup fail
with CUDA_ERROR_OUT_OF_MEMORY, exit 187. The playlist generator took
that for a bad file and wrote playlist.unsupported, so the video never
played; preview clips were marked failed the same way.

is_gpu_init_failure() recognises CUDA/NVENC setup errors in ffmpeg's
stderr. When an NVENC run fails that way, the playlist and the preview
clip rerun once on libx264. A file that also fails on the CPU still gets
the sentinel. The HLS command and the timed run are pulled out of the
handler (hls_command, run_ffmpeg) so both attempts share them.

Fixes #215
