patch 8.2.0533: tests using term_wait() can still be flaky

Commit: https://github.com/vim/vim/commit/6a2c5a7dd5c9215cc030d5ea6e4616d782c091dd

    patch 8.2.0533: tests using term_wait() can still be flaky

    Problem:    Tests using term_wait() can still be flaky.
    Solution:   Increase the wait time when rerunning a test. (James McCoy,
                closes #5899)  Halve the initial times to make tests run faster
                when there is no rerun.
