selftests/damon/damos_tried_regions: fix expectation output and join TypeError

Browse Source 
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.
