charset_conv: fix "auto" fallback with uchardet not compiled

Tried to open iconv with "auto" as source codepage, instead of using
the latin1 fallback. This also neutralizes the libavcodec dumbass
UTF-8 check, which discards subtitles not in UTF-8 and shows an
error message for ffmpeg CLI instead.

Fixes #3954.
