Subject: [PATCH] tests: (blkid) add support for multisession images

This commit adds support for multisession filesystem images to
standard low-probe blkid tests. The expected image name is

 <name>-multi-<offset>[-<offset> ...][-<something>].img

For example:
  iso-multi-0-174-348-genisoimage.img.xz

triggers three sub-tests:
  : iso-multi-genisoimage-0     ... OK
  : iso-multi-genisoimage-174   ... OK
  : iso-multi-genisoimage-348   ... OK

Addresses: https://github.com/karelzak/util-linux/issues/1161
