This patch resolves a situation that causes an annoying warning, "cannot open filetypes.conf". The warning discussed in more detail here https://issues.guix.gnu.org/68948

To see the warning from the unpatched version, this shell command,
```
$ echo "(highlight (package bug))" | highlight -O xterm256 --syntax lisp
cannot open filetypes.conf: No such file or directory
(highlight (package bug))
```

Using the patched package definition, no warning is seen
