Marco Trevisan (Treviño) a0e71ff86f 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
