[Qemu-block] [PATCH for 3.1? or 4 v4 1/1] qemu-iotests: Don't run the test when user is root

[Farhan Ali]

Test 232 creates image files with read-only permission and
expects an error message when trying to access the image
files with read-only and auto-read-only turned off.

Don't run as root user, since root can open files with read/write
access for read-only files.
