    gio-tool-mount: Return early on fgets EOF
    
    As per commit a5390002 we're exiting with error in case fgets failed,
    however it could also fail because of EOF (like on ^D), so in such case
    we can just return early treating it as a non-error.
    
    Otherwise still exit with error.
    
    Fixes: #2737
