Running
git grep '\$here' tests/qemu-iotests
has 0 hits, which means we are setting a variable that has
no use. It appears that commit e8f8624d removed the last
use. So execute the following cmd to remove all of
the 'here=...' lines as dead code.
sed -i '/^here=/d' $(git grep -l '^here=' tests/qemu-iotests)
