media-libs/freetype: security bump for CVE-2020-15999

This vulnerability is being exploited in the wild;
this fix is identical to that being used in Chromium
as a band-aid for now (also in upstream git).

See upstream bug for more information.

Bug: https://bugs.gentoo.org/750275
Package-Manager: Portage-3.0.8, Repoman-3.0.1
