fuse: use fuse3 as default. #150502
Description
Describe the bug:
fuse3 has a bunch of updates that whitelist various file systems, exfat, bcachefs, etc.
nix-shell -p '(gocryptfs.override {fuse=fuse3;}).overrideAttrs (attrs: {propagatedBuildInputs = attrs.propagatedBuildInputs ++ [fuse3];})' fuse3

/run/wrappers/bin/fusermount: mounting over filesystem type 0xca451a4e is forbidden
fs.Mount failed: fusermount exited with code 256
fusermount is hardcoded here: https://github.com/hanwen/go-fuse/blob/3ab5d95a30ae25019bf030a2bab076dba61c27da/fuse/mount_linux.go#L219
but nixos packages fuse3 as fusermount3
Maybe it's time to make fuse3 the "default" as it's 4 years old, and fuse2 should explicitly provide fusermount2
