Add a test case to zbd group to check that zones sector mapping correctness for
zoned block devices that are not an entire full device (null_block device or
physical device). These logical devices are for now partition devices or
device-mapper devices (dm-linear or dm-flakey). It catches regressions of
complex zone remapping problem fixed by commit 9864cd5dc54c "dm: fix report zone
remapping to account for partition offset".

Changes from v2:
* Reflected review comments on the list
* Modified _get_dev_path_by_id() to get device paths of partition devices

Changes from v1:
* Reflected Chaitanya's review comments on the list
* Separated helper functions in zbd/rc into a preparation patch

  zbd/rc: Introduce helper functions for zone mapping test
  zbd/007: Add zone mapping test for logical devices
