fix(dmsquash-live-autooverlay): re-read partition table after creation

After parted creates the overlay partition, the kernel's in-memory
partition table is not automatically updated. This causes mkfs to fail
with "The file /dev/sdX does not exist" on some systems.

Add blockdev --rereadpt to force the kernel to re-read the partition
table before attempting to create the filesystem.
