Ondrej Kozina 002f73b360 Add --shared option in veritysetup open action.
The option allows data device to be used in multiple
DM table mappings and exclusive access is not checked
anymore in-before device activation.

It also allows correct concurrent verity device activation.
With --shared option if multiple processes compete for same DM
verity name using same underlying data device we can now guarantee
one process succeeds and all other fails with -EEXIST.
