Address issues detected by shellcheck SC2003:
  expr is antiquated. Consider rewriting this using $((..)), ${} or [[ ]].

The following statement in portable_signatures.test causes the issue:

  expr index "$TST_LIST" "check_evm_revalidate"

The man page for expr states:

       index STRING CHARS
              index in STRING where any CHARS is found, or 0

The intention is certainly not to find an index of any of the characters
in "check_evm_revalidate" in $TST_LIST but to find the word
"check_evm_revalidate" in $TST_LIST. Therefore, use grep -w to determine
whether the word is there.
