(cherry picked from commit 7ab7ecfcfe)
tftpd: Check the server status after each test.
* In the setup phase, wait for the server to start (or fail to start)
before proceeding with the test. This makes it possible to write test
cases that don't expect a response from the server without ending up
in a race over the server PID file.
* After running each test, wait up to 30 seconds for the server to exit
and check that the exit status matches what the test case says to
expect (usually 0).
* We still kill and collect the server in the cleanup phase, in case the
test ended early.
