Security update, fixes CVE-2022-37434 in zlib.
Only applications exposing/using `inflateGetHeader()` seem to be affected,
which is not our case, so this is not critical for Godot.
Remove duplicated copy of zlib in freetype sources to force using the updated
version in `thirdparty/zlib/`.

Security update, fixes CVE-2018-25032 in zlib.
Preliminary assessment doesn't show Godot as affected since we don't
seem to call `deflate` with the problematic parameters, but the extent
of the vulnerability is not fully clear upstream yet.
