udev: import previous results of blkid when in suspended state

Follow-up for e10f67e91728f1e576803df884049ecbd92874d0.

The commit e10f67e91728f1e576803df884049ecbd92874d0 tries to keep device
node symlinks even if the device is in the suspended state. However,
necessary properties that may previously obtained by the blkid command
were not imported at least in the .rules file. So, unless ID_FS_xyz
properties are imported by another earlier .rules file, the device node
symlinks are still lost when event is processed in the suspended state.

Let's explicitly import the necessary properties.
