Sometimes we need to skip to a line but it includes addresses or other information which can vary depending on the runtime conditions.
Add a new ut_assert_skip_to_linen() which is similar to the existing ut_assert_skip_to_line() function but only checks that the console line matches up to the length of the provided string.
