[PATCH 1/3] util/grub-file: Fix error message on --version

[Lukas Fink]

Hello,

I found a few bugs in the grub-file utility and the corresponding
command.

The first is that "grub-file --version" prints an error message:
grub-file (GRUB) 2.04
error: unknown argument `--version'.

The attached patch fixes this.

Greetings

Lukas Fink

grub-file now exits after printing its version, therefore avoiding to
print an unknown argument error message.
