libfreetype: update to 2.8.1, fix host install issue

This commit updates Freetype 2 to the latest upstream version and fixes
the issue where freetype-config was incorrectly installed into the
host, rather than the target, staging directory, therefore causing
compilation issues with other packages that depend on libfreetype.
