Subject: [PATCH] fuzzer_set_property: fix setting audio-files list

`:` were not escaped correctly. Also while at it clear other external
file lists, as we don't want to load any. Subtitle fuzzer will be added
in the future.

It is surprisingly hard to clear the list with C API. That needs whole
mpv_node_list with 0 elements, to make it clear it.
