bug#71421: system info in test-suite.log

[Karl Berry]

    I've attached a patch that I think handles that 

Thanks Collin. I installed it (with minor wording tweaks).

    and the extra space you mentioned.

I had thought the extra space was useful rather than confusing,
indicating that a word had been omitted from the output. But I'm fine
with leaving it out. -k

test: Improve output of system information in test-suite.log.

Fixes https://bugs.gnu.org/71421.

* lib/am/check.am ($(TEST_SUITE_LOG): Use $(AWK) instead of 'awk'.
Remove an extra space in uname output.  Start the line with
"System information", and other sections with "Distribution
information".
* NEWS: add reference to #71421.
