Subject: selftests/damon/drgn_dump_damon_status: dump damos->migrate_dests

drgn_dump_damon_status.py is a script for dumping DAMON internal status in
json format. It is being used for seeing if DAMON parameters that are set
using _damon_sysfs.py are actually passed to DAMON in the kernel space.
It is, however, not dumping full DAMON internal status, and it makes
increasing test coverage difficult. Add damos->migrate_dests dumping for
more tests.
