[PATCH] tests/qemu-iotests/testrunner: Supply a test plan in TAP mode

[Thomas Huth]

Quoting the TAP specification: "The plan tells how many tests will be
run [...]. It’s a check that the test file hasn’t stopped prematurely."
That's a good idea of course, so let's support that in the iotest
testrunner, too.
