qemu-img: Flush stdout before before potential stderr messages

During 'qemu-img create ... 2>&1', if --quiet is not in force, we can
end up with buffered I/O in stdout that was produced before failu

qemu-img: Flush stdout before before potential stderr messages

During 'qemu-img create ... 2>&1', if --quiet is not in force, we can
end up with buffered I/O in stdout that was produced before failure,
but which appears in output after failure. This is confusing; the fix
is to flush stdout prior to attempting anything that might produce an
error message. Several iotests demonstrate the resulting ordering
change now that the merged outputs now reflect chronology. (An even
better fix would be to avoid printf from within block.c altogether,
but that's much more invasive...)

qemu-iotests: adding LUKS cleanup for non-UTF8 secret error

This patch adds a new test file to exercise the case where
qemu-img fails to complete for the LUKS format when a non-UTF8
secret is used.
