Respect OFFSET_CAPTURE when padding preg_match_all() results

Browse source 
This issue was mentioned in bug #73948. The PREG_PATTERN_ORDER
padding was performed without respecting the PREF_OFFSET_CAPTURE
flag, which resulted in unmatched subpatterns being either null or
[null, -1] depending on where they occur. Now they will always be
[null, -1], consistent with other usages.
