Subject: [PATCH 14/16] xdg-mime: return correct exit code for GNOME

If the desktop environment was GNOME and none of the commands for
detecting the MIME type of a file was available, xdg-mime used to return
exit code 0 even though it failed. The man page says it should return
exit code 3. This commit fixes the issue.

I have considered returning exit code 4 instead since that is what would
be returned if info_kde() or info_generic() fail to find a tool for MIME
type detection. But I have decided to implement the behavior as
specified in the man page.

The exit code of an if construct is 0 if no condition
tested true [^1]. The author of the original code probably was not aware
of this.
