Subject: Plumb VFS2 imported fds into virtual filesystem.

- When setting up the virtual filesystem, mount a host.filesystem to contain
  all files that need to be imported.
- Make read/preadv syscalls to the host in cases where preadv2 may not be
  supported yet (likewise for writing).
- Make save/restore functions in kernel/kernel.go return early if vfs2 is
  enabled.
