Dynamic fixture dependencies are now shown in setuponly and setupshow

[Anton3]

Minimal reproducer:

import pytest

@pytest.fixture()
def dynamically_requested_fixture():
    pass

@pytest.fixture()
def dependent_fixture(request):
    request.getfixturevalue('dynamically_requested_fixture')

def test_dyn(dependent_fixture):
    pass

Expected output with --setuponly:

SETUP    F dependent_fixture (fixtures used: dynamically_requested_fixture)

Actual output:

SETUP    F dependent_fixture
