On platforms that support native coverage (introduced in Erlang/OTP 27), the `cover` module did not properly handle failed calls to `code:get_coverage/2`. The call to that function will fail if the module in question has been reloaded or unloaded. For example, if `cover:export/1` was called and a module had been reloaded on a remote node (for example by `meck`), the `cover:export/1` call would never return. Because the current API for `cover` has no good way to report this kind of error, we will fix the issue by logging the failed call using the `logger` module and otherwise ignore the failure. That implies that there will be no coverage information for modules that have been reloaded. That is compatible with the behavior of `cover` prior to Erlang/OTP 27. Closes erlang#8691

This PR tries to fix #8661. @arcusfelis suggested this solution on OTP's end.
Now a
cover_serverprocess on remote node will crash when a process spawned by it crashes. This is better than thecover_serverprocess never knowing about the crash.
