bug#22050: fuse.ko not automatically loaded on GuixSD

[Ludovic Courtès]

On GuixSD, fuse.ko is not automatically loaded when someone tries to
access /dev/fuse:

--8<---------------cut here---------------start------------->8---
$ sshfs SOMEHOST /tmp/x
fuse: device not found, try 'modprobe fuse' first
--8<---------------cut here---------------end--------------->8---

We do have FUSE’s udev rules installed by default, but they don’t seem
to do much:

--8<---------------cut here---------------start------------->8---
50-udev-default.rules:75:KERNEL=="fuse", MODE="0666", 
OPTIONS+="static_node=fuse"
99-fuse.rules:1:KERNEL=="fuse", MODE="0666"
--8<---------------cut here---------------end--------------->8---
