Add unprivileged option in `mount.fuse3`
The unprivileged option allows to run the FUSE file system process
without privileges by dropping capabilities and preventing them from
being re-acquired via setuid / fscaps etc. To accomplish this,
mount.fuse sets up the `/dev/fuse` file descriptor and mount itself
and passes the file descriptor via the `/dev/fd/%u` mountpoint syntax
to the FUSE file system.
