fix how tools check exit codes an entire pipe

We use the `status_codes=("${PIPESTATUS[@]}")` method to
collect all of the bash exit codes from a pipe in one go,
and then test for any failure with `[[ ${status_codes[*]} =~ [1-9] ]]`.

There are other cases where an exit code is obtained,
however in each of those cases only a single exit code
from just one of the commands in the pipe is needed.

In `bin/gen-sitemap.sh` changed VERSION from "1.3.9 2024-06-21"
to "1.3.10 2024-07-18".

In `bin/gen-status.sh` changed VERSION from "1.5.4 2024-07-18"
to "1.5.5 2024-07-18".

Performed `make www` to accomplish the above and to test under macOS.
