7187c7bbb8 (t4210: skip i18n tests that don't work on FreeBSD, 2019-11-27) adds a REG_ILLSEQ prerequisite, and to do that copies the common branch in test-lib and expands it to include it in a special case for FreeBSD. Instead; test for it using a previously added extension to test-tool and use that, together with a function that identifies when regcomp/regexec will be called with broken patterns to avoid any test that would otherwise rely on undefined behaviour. The description of the first test which wasn't accurate has been corrected, and the test rearranged for clarity, including a helper function that avoids overly long lines. Only the affected engines will have their tests suppressed, also including "fixed" if the PCRE optimization that uses LIBPCRE2 since b65abcafc7 (grep: use PCRE v2 for optimized fixed-string search, 2019-07-01) is not available.
