ext/pcre: drop negative-length match tests

Browse Source 
Newer PCRE2 rejects \K in lookarounds at compile time, so the
negative-length match code path can no longer be triggered from
userland PHP. The PCRE2_EXTRA_ALLOW_LOOKAROUND_BSK flag that would
re-enable it is only settable via the C compile context API.
