osd_libass: fix stupid dangling pointer crash 

append_utf8_buffer() reallocates the buffer passed to it, and returns
the new pointer.

This bug was originally introduced in mplayer2 when that project merged
mpv's osd_libass.c. That merge changed some minor things, including ASS
escape handling. When mpv used this better method of escape handling too
(commit 0ff7dd992f), the bug was duplicated.
