<!-- ^ Please provide a concise and informative title. -->
<!-- ^ Don't put issue numbers in the title, do this in the PR
description below. -->
<!-- ^ For example, instead of "Fixes sagemath#12345" use "Introduce new method
to calculate 1 + 2". -->
<!-- v Describe your changes below in detail. -->
<!-- v Why is this change required? What problem does it solve? -->
<!-- v If this PR resolves an open issue, please link to it here. For
example, "Fixes sagemath#12345". -->

A minor follow-up after sagemath#37391:

Seen for example in
https://github.com/sagemath/sage/actions/runs/8626379356/job/23644513913
?pr=37570#step:11:3227:
```
sagemath#24 4091.8 /sage/build/bin/sage-logger: line 66: /usr/bin/time: No such
file or directory
sagemath#24 4091.8 [sagemath_doc_html-none] installing. Log file:
/sage/logs/pkgs/sagemath_doc_html-none.log
sagemath#24 5807.5 cat: /sage/logs/pkgs/sagemath_doc_html-none.time: No such
file or directory
```
We suppress these (harmless) messages which show up when `/usr/bin/time`
is not available.
