samples/damon/mtier: replace damon_add_region() with damon_set_regions()

mtier DAMON sample module and DAMON virtual address operation set (vaddr)
unit tests are using damon_add_region() for setup of DAMON monitoring
target region boundaries setup.  But, damon_set_regions() is designed for
exactly the purpose.  All other DAMON API callers use the function for the
purpose.  Replace damon_add_region() usage in mtier sample module with
damon_set_regions(), for unifying the use case and reducing the
maintenance cost.
