Random failures from DeleteAllProfiles unit test

[afbjorklund]

Due to it making direct calls to docker, and finding profiles outside the test context.

--- FAIL: TestDeleteAllProfiles (0.20s)
    delete_test.go:203: ListProfiles length = 9, expected 8
        valid: []
        invalid: [0xc000d73320 0xc000d73350 0xc000d73380 0xc000d733b0 0xc000d733e0 0xc000d73410 0xc000d73440 0xc000d73470 0xc000d734d0]

There should be a mocked docker (oci.Docker), similar to the mock miniHome.

        pDirs, err := profileDirs(miniHome...)

        cs, err := oci.ListOwnedContainers(oci.Docker)

                        err = os.Setenv(localpath.MinikubeHome, td)

The invalid profiles are:

[p1 p2_empty_profile_config p3_invalid_profile_config p4_partial_profile_config p5_missing_machine_config p6_empty_machine_config p7_invalid_machine_config p8_partial_machine_config minikube]

It also shouldn't just make random calls to Docker like that, but that's another story. (#8577)

TestListProfiles also got the wrong result, but it didn't validate properly.

-- FAIL: TestListProfiles (0.10s)
    profile_test.go:59: ListProfiles length = 6, expected 5
