mpv crashed on quit when it was run using the bundle functionality and started without any files thus waiting for file open events. In that case, since there is no key_fifo initialized yet, short circuit to `terminate_cocoa_application()` which is generally called from `exit_player()` during normal lifecycle. Fixes bug report from user `eng` on IRC.
