UPSTREAM: lkdtm: Add tests for struct list corruption
(cherry-picked from 6819d101dd739dd4e8cbe60a98c9ebb224ecc992)
When building under CONFIG_DEBUG_LIST, list addition and removal will be
sanity-checked. This validates that the check is working as expected by
setting up classic corruption attacks against list manipulations, available
with the new lkdtm tests CORRUPT_LIST_ADD and CORRUPT_LIST_DEL.
