[freetype2] master 007c109: * src/sfnt/pngshim.c (Load_SBit_Png): Fix memory leak (#59322).

[Werner LEMBERG]

branch: master
commit 007c109b4594c5e63948bd08b4d5011ad76ffb10
Author: Ben Wagner <bungeman@google.com>
Commit: Werner Lemberg <wl@gnu.org>

    * src/sfnt/pngshim.c (Load_SBit_Png): Fix memory leak (#59322).
    
    The issue is that `rows` is allocated but will not be freed in the
    event that the call to `png_read_image` fails and calls `longjmp`.
