Speed up tests with background sleep

Until now, a significant part of test run time was spent waiting
TEST_QUERY_DELAY seconds for a response from the server. The sleep call
used for that keeps the pipe from the subshell to gnutls-cli open,
without it, gnutls-cli would terminate as soon as sed is done, leading
to failing tests. However, in many cases the wait is longer than
necessary for the test.

Sending sleep to the background allows the test case to proceed instead
of waiting for sleep to return, but has the disadvantage of leaving the
sleep process dangling until it eventually times out. I think the
significantly reduced test execution time is worth it.
