D3443: tests: remove pid file by default

REVISION SUMMARY
  Previously, killdaemons.py would kill PIDs listed in a file then
  leave the file lingering around.
  
  If the PIDs are killed, then there's no point leaving the PID file
  around. In the worst case, a later invocation of killdaemons.py
  (run-tests.py invokes killdaemons.py after running a test) could kill
  a separate process whose PID conflicted with a previously-killed
  process. By removing the PID file, we eliminate this possibility.
  
  Some tests were manually removing the PID file after calling
  killdaemons.py. So we update these tests to not do this.
