7187c7bbb8 (t4210: skip i18n tests that don't work on FreeBSD, 2019-11-27)
adds a REG_ILLSEQ prerequisite to avoid failures from the tests added with
4e2443b181 (log tests: test regex backends in "--encode=<enc>" tests,
2019-06-28), but hardcodes it to be only enabled for FreeBSD.
Instead of hardcoding the affected platform, add a test using test-tool to
make sure it can be dynamically detected in other affected systems (like
DragonFlyBSD or macOS), and while at it, enhance the tool so it can report
better on the cause of failure and be silent when needed.
To minimize changes, it is assumed the regcomp error is of the right type
since we control the only caller, and is also assumed to affect both basic
and extended syntax (only extended is tested, but both behave the same in
all three affected platforms).
The description of the first test which wasn't accurate has been corrected,
and unlike the original fix from 7187c7bbb8, all added entries to test-lib
are no longer needed and only the 2 affected engines will have their tests
suppressed.
