Draft: fix build error
Without this fix, during a build with gst-build I have this error message:
ld: gst-build/build/tmp-introspectn2qy5jmv/GstTranscoder-1.0.o:(.data.rel+0x8): undefined reference to `gst_transcoder_state_get_type`
ld: gst-build/build/tmp-introspectn2qy5jmv/GstTranscoder-1.0.o:(.data.rel+0x10): undefined reference to `gst_transcoder_message_get_type`
ld: gst-build/build/tmp-introspectn2qy5jmv/GstTranscoder-1.0.o:(.data.rel+0x20): undefined reference to `gst_transcoder_signal_adapter_get_type`
The sources must be comma separated in meson scripts
