    build: Only enable freetype if fontconfig is also available
    
    This changes meson.build to match what configure.ac already does. The
    code doesn’t have separate conditions for whether fontconfig and
    freetype are available: if freetype compilation is enabled, it assumes
    that fontconfig is also available.
    
    Previously, systems with freetype available, but no fontconfig, would
    fail to compile Pango due to trying to link against non-existent
    fontconfig symbols.
