Fix handling of "undef" in contrib/jsonb_plperl.

Perl has multiple internal representations of "undef", and just
testing for SvTYPE(x) == SVt_NULL doesn't recognize all of them,
leading to "cannot transform this Perl type to jsonb" errors.
Use the approved test SvOK() instead.

Report and patch by Ivan Panchenko.  Back-patch to v11 where
this module was added.
