We are going to drop group file. Define group in tests as a preparatory
step.
The patch is generated by
cd tests/qemu-iotests
grep '^[0-9]\{3\} ' group | while read line; do
file=$(awk '{print $1}' <<< "$line");
groups=$(sed -e 's/^... //' <<< "$line");
awk "NR==2{print \"# group: $groups\"}1" $file > tmp;
cat tmp > $file;
done
