fix(wpa_supplicant): add crypto init calls to address memory leak issue in tests

Browse Source 
- C61 does not feature MPI hardware and hence the other tests were
  getting executed first
- Memory leak threshold should be independent of target crypto
  peripherals and hence added to crypto init to test `setUp` call
