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

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)
