Bash is not always installed as /bin/bash. In particular on OpenBSD,
the package installs it in /usr/local/bin.
Use the 'env' shebang to search bash in the $PATH.
Patch created mechanically by running:
$ git grep -lE '#! ?/bin/bash' -- tests/qemu-iotests \
| while read f; do \
sed -i 's|^#!.\?/bin/bash$|#!/usr/bin/env bash|' $f; \
done
