[PATCH] iotests: Allow running from different directory
It is convenient to be able to edit the tests and run them without changing the current working directory back and forth. Instead of assuming that $PWD is the qemu-iotests build directory, derive the build directory from the executed script. This allows 'check' to find the required files even when called from another directory. The scratch directory will still be in the current working directory.
