fuse: 2.9.7 -> 2.9.8 (security, CVE-2018-10906)

Upstream changelog:
- SECURITY UPDATE: In previous versions of libfuse it was possible to
  for unprivileged users to specify the allow_other option even when
  this was forbidden in /etc/fuse.conf. The vulnerability is present
  only on systems where SELinux is active (including in permissive
  mode).
- libfuse no longer segfaults when fuse_interrupted() is called outside
  the event loop.
- The fusermount binary has been hardened in several ways to reduce
  potential attack surface. Most importantly, mountpoints and mount
  options must now match a hard-coded whitelist. It is expected that
  this whitelist covers all regular use-cases.
- Fixed rename deadlock on FreeBSD.
