Yu Watanabe f808abd51b integration-tests: adjust priorities ...

When running with sanitizers:
```
26/95 systemd:integration-tests / TEST-21-DFUZZER                          OK 1517.75s
40/95 systemd:integration-tests / TEST-85-NETWORK-NetworkdDHCPClientTests  OK  779.18s
42/95 systemd:integration-tests / TEST-04-JOURNAL                          OK  716.17s
```
and without sanitizers:
```
44/95 systemd:integration-tests / TEST-85-NETWORK-NetworkdDHCPClientTests  OK  730.33s
29/95 systemd:integration-tests / TEST-64-UDEV-STORAGE-simultaneous_events OK  701.49s
40/95 systemd:integration-tests / TEST-04-JOURNAL                          OK  348.05s
```

So, let's set higher priorities only on these tests.
