bug#62983: workaround PCRE2 bug affecting at least \D and \W

[Carlo Marcelo Arenas Belón]

All versions of PCRE2 that include PCRE2_MATCH_INVALID_UTF had a bug on
its JIT implementation that results in failure to match for the negative
perl classes, and seems to be easier to replicate when the matching
character is a multibyte one.

Disable that flag and use the original fallback instead.

Alternatively JIT could be disabled instead, but the option selected has
less of an impact on performance.
