Denton Gentry 8578b0445d tstun: add test to send a packet after Close()
This test serves two purposes:
+ check that Write() returns an error if the tstun has been
  closed.
+ ensure that the close-related code in tstun is exercised in
  a test case. We were getting spurious code coverage adds/drops
  based on timing of when the test case finished.
