export: Deal with NFS filesystems
When a NFS filesystem is exported usually NFSD refuses
to export the filesystem because mountd was unable to provide
an UUID and the kernel cannot derive a dev it from the NFS client
super block.
To deal with this situation, teach uuid_by_path() how to generate
an UUID from a NFS filesystem.
Using /proc/fs/nfsfs/volumes it is possible to find the NFS fsid
from the backend and use it as seed for mountd's UUID mechanism.
