Update go-fuse import path to github.com/hanwen/go-fuse/v2

We need
https://github.com/hanwen/go-fuse/commit/fd7328faf9fdf75709f7ba7df7072aaf4eeb18b3
to fix a crash reported in https://github.com/rfjakob/gocryptfs/issues/430 :

  2019/10/30 17:14:16 Unknown opcode 2016
  panic: runtime error: invalid memory address or nil pointer dereference
  [signal SIGSEGV: segmentation violation code=0x1 addr=0x20 pc=0x508d38]

This patch is only in the v2.x.x branch. Upgrade to v2, as the
old API is also supported there.

Running

  git grep hanwen/go-fuse | grep -v hanwen/go-fuse/v2

to check for forgotten references comes back clean.
