remove rsyncdir usage since pytest-xdist has deprecated it

[matthias-margin]

This removes the usage of rsyncdir so that pytest-xdist does not raise a deprecation warning. Trying to get all warning in my projects to go away.

Issue submitted a bit ago #621 and a older one too #557

@ionelmc it seems like this should be merged. You said yourself in #557 (comment)

Well I guess there could be another pytest-cov release outright removing the rsync stuff. Would that make everyone happy?

And the response to your question seems to be a clear yes:

• ~10 thumbs up in response to your comment
• other comments going in the same direction in the same issue
• this PR that was opened to fix it and Remove usage of deprecated rsyncdir, which will be removed in pytest-xdist 4.0 #621 that was opened to say that the problem still exists even if pytest-cov is incompatible with pytest-xdist 3.x due to injection of rsync option #557 has been closed

@ionelmc pinging as well, a merge of this PR and a new release would be appreciated.

It's in master now (rebased).

Thanks for taking care about this! This patch is now in 5.0.0, but it hasn't been rolled out to pypi. Could someone take care of that?

[ionelmc]

Yeah, this weekend I'll have time for it.
