[PVE-User] vzmigrate: use --sparse on the first rsync

[John O. Stevens]

I thought that vzdump was called during migration of containers,
but it seems it's not, so I added the same option to the first
rsync in vzmigrate, to help with sparse files during a migration.

I tested it with:

  vzmigrate -r no --keep-dst -v host2 CTID

And with this patch, sparse files are not expanded, as expected.
