TestProcesses failing on CI for darwin

[AndersonQ]

The TestProcesses is constantly failing on CI at least for #144, but it seems to be happening on other PRs as well, even though it passes locally.

I don´t have a mac to investigate it further, I just got someone else to try it and as I said, itś working locally.

This test looks non-deterministic in that it lists all processes and assumes the first one has an executable associated to it. If macos is like Linux and Windows, then this is not always true for special kernel processes.

Lines 98 to 108 in 53d6396

	func TestProcesses(t *testing.T) {
	var s darwinSystem
	ps, err := s.Processes()
	if err != nil {
	t.Fatal(err)
	}
	pinfo, err := ps[0].Info()
	if err != nil {
	t.Fatal(err)
	}

I think we should update the test's error message to include the full process details so we can see what process is causing this.

I opened a PR to address this at #150.
