Subject: [PATCH] Travis Mac: set PKG_CONFIG_PATH to use custom freetype
 installation

Somehow the freetype-config script needs this now to report our custom installation not the system one (which may not exist). I'm not sure why it worked before the dependecy update but maybe the builds scripts in FTGL fixed that for us in the past.
