Can customize config fallback directory

CMake takes a `FALLBACK_CONFIG_DIR` flag which is the directory where the
standard configuration file `config` is copied at installation.
If loading from typical configuration directories fails, sway loads
FALLBACK_CONFIG_DIR/config (/etc/sway/config by default).
