Subject: vim-patch:8.2.3510: changes are only detected with one second
 accuracy

Problem:    Changes are only detected with one second accuracy.
Solution:   Use the nanosecond time if possible.  (Leah Neukirchen,
            closes vim/vim#8873, closes vim/vim#8875)
https://github.com/vim/vim/commit/0a7984af5601323fae7b3398f05a48087db7b767

In Nvim Test_checktime_fast() is also flaky. Add a delay to avoid that.
