libav: Fix for APNG encoder property registration
The AVClass name of Animated PNG in FFmpeg 5.x is "(A)PNG" and it will be converted to "-a-png" through g_ascii_strdown() and g_strcanon(). But GLib disallow leading '-' character for a GType name. Strip leading '-' to workaround it. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/2733>
