selftests: ublk: don't share backing files between ublk servers
stress_04 is missing a wait between blocks of tests, meaning multiple
ublk servers will be running in parallel using the same backing files.
Add a wait after each section to ensure each backing file is in use by a
single ublk server at a time.
