CMake builds: Fix builds

Include the fallback sources in the build, and update
src/Makefile.sources so that it can be read by the CMake build files.

Fix a typo in the DirectWrite configure option so that we can properly
enable DirectWrite builds.

Also, when building the utility program, install them as well.
