Display the label of encrypted file systems (#760080)

Browse source 
LUKS headers don't provide any concept of label.  Also there is already
the method Partition::get_filesystem_label() for getting the *file
system* label, so virtualise it and provide an appropriate
implementation to get the label of an encrypted file system represented
within a derived PartitionLUKS object.  This causes the label to be
displayed correctly in the main window.

It also happens to display the encrypted file system label in the
Information dialog for a LUKS formatted partition.  However the whole
Information dialog will be addressed differently in a following commit.
