Add PartitionLUKS class and create objects (#760080)

Absolute minimum implementation of a PartitionLUKS class which can be
constructed, polymorphically copied and destroyed.  Contains an
"encrypted" member of type Partition to represent the encrypted file
system within the LUKS format.

Create PartitionLUKS objects instead of base Partition objects when a
LUKS formatted partition is found.  Only the base Partition object
member values have been populated, and the "encrypted" member remains
blank at this point.

Bug 760080 - Implement read-only LUKS support
