Fix openssl-3.0 issue involving ASN1 xxx_it

Use ASN1_ITEM_rptr() instead of taking the address of IDC_PEID_it.

openssl-3.0 changed the type of TYPE_it from `const ASN1_ITEM TYPE_it` to
`const ASN1_ITEM *TYPE_it(void)`. This was previously hidden behind
OPENSSL_EXPORT_VAR_AS_FUNCTION but in 3.0 only the function version is
available. This change should have been transparent to the application, but
only if the `ASN1_ITEM_rptr()` macro is used.

This change passes `make check` with both openssl 1.1 and 3.0.
