[PATCH v2 1/2] iotests: add another bash sleep command to 247

[Andrey Shinkevich via <qemu-devel@nongnu.org>]

This patch paves the way for the one that follows. The following patch
makes the QMP monitor to read up to 4K from stdin at once. That results
in running the bash 'sleep' command before the _qemu_proc_exec() starts
in subshell. Another 'sleep' command with an unobtrusive 'query-status'
plays as a workaround.
