runner: Flush igt_runner outputs before forking

If the output of igt_runner is piped or redirected, buffered prints
could be left lingering and read as test executable output if execv()
fails. This can happen easily if CI for example generates a testlist
with an incorrect binary name, or an optional test binary (say,
kms_chamelium) is not built for the deployment in question.
