control c killing just mpv and not sfm

[Mattio-cmd]

Make it so sfm does not closes itself after pressing control c in mpv/sxiv.

My idea is making it so mpv stops running after i kill it with control c but sfm stays

Hi @Mattio-cmd,
sfm fork then exec, of course you can kill the parent PID

kill(main_pid, sig);
