tests/bsim host/privacy/peripheral: Minor fixes to allow equality check

Minor fixes in this test script to:
* Start with an empty flash even if there was a left over flash file
  on disk
* Not overwrite the simulation activity from the first part of the test
  in the second part of the test, to allow looking into the
  traffic and to allow rerunning the test in check mode, to ensure
  there is no radio activity changes when another change is done.
* Set the simulation id to something more unique (it was just
  "peripheral" before which is too easy to be repeated in another
  test)
