print/freetype2: Update to 2.11.0, convert to CMake and rearrange Makefile

[diizzy]

Summary

• Convert to CMake, reduces patching and builds faster
• Clean up MASTER_SITES and use SAVANNAH alias
• Rearrange Makefile to make it easier to read and follow
• Patch CMake(Lists.txt) to mimic GNU Autotools

This change removes freetype-config which isn't a default option and majority of distros does not ship it and static library.
