Follow-up to previous Solaris/S_regmatch commit

PL_charclass is the thing being temporarily #defined to something else, so
it's the thing that needs #undeffing at the end, not pl_charclass_dup.

Doesn't make any difference at the moment, but would if at some point
a function following S_regmatch() started making use of PL_charclass.
