VTS: fix RadioHidlTest.getAvailableNetworks issue

Analysis: VtsHalRadioV1_0Target's timeout is too short for
getAvailableNetworks, because this request duration depends on NW
environment or frequency.

Suggested solution: Add a timeout parameter to wait() and default
timeout value is 5 minutes in order to avoid timeout fail due to NW
environment.

Bug: 68834032
Test: getAvailableNetworks can be passed after we apply this patch and
      test result for all other telephony 1.0 and 1.1 test cases are not
      changed.
