utils: Fix options injection with custom filename
If a filename start by '--', grep would assume this is a option,
and so would potentially either miss the file, or wait
until STDIN is closed. A quick look at grep manpage do not
yield any way to execute code with this for now, but it is
better to fix the problem for now.
Using '--' is the traditional way to deal with file using
a double dash prefix.
When using RetroRunner, this helps ensuring we unload the game, deinit
the core, and by extension that cores saving on unload save as expected
when quitting the application.
