libblkid: remove obsolete tags from cache

The libblkid cache tags are not removed if a new version of the
tags is empty (e.g. label 'foo' -> '').

 # mkfs.ext4 -L test_label /dev/sda15
 # blkid /dev/sda15
 /dev/sda15: LABEL="test_label"

 # tune2fs -L '' /dev/sda15
 # blkid /dev/sda15
 /dev/sda15: LABEL="test_label"
                    ^^^^^^^^^^
