[PATCH v2 2/3] selftests/damon/damos_tried_regions: fix expectation output and join TypeError

[Kunwu Chan <kunwu.chan@linux.dev>]

From: Kunwu Chan <chentao@kylinos.cn>

The expectation print has wrong operator precedence: '%' binds
before the conditional expression, so the else branch prints
'not met' without the prefix 'expectation (>= 14) is'.  Add
parentheses to fix it.

Also, '\n'.join() on the list of ints raises TypeError;
convert to str in the list comprehension.
