basesrc-test: Fix race testing segment update

As this test is using a short sleep (GST_USECOND, which is 10ms
in microsecond), sometimes that EOS event is received before the
loop in basesrc have run _do_seek() and pushed the update segment.
To solve this issue, we wait for the initial segment (and flush it)
then we wait for the second segment before sending EOS.
