Ruben Gonzalez 75bcdc4564 avmux: Fix crash when muxer doesn't get codecid 
gst_ffmpeg_formatid_get_codecids from gst_ffmpegmux_base_init to gst_ffmpegmux_base_init

FFmpeg 7.0 included new muxer rcwt for Raw Captions with Time
(RCWT). Commit [1].  GStreamer couldn't get sink caps for muxer it.

Calling gst_ffmpeg_formatid_get_codecids in gst_ffmpegmux_register to
avoid create muxer without pad templates.
