Test failure on 32-bit

[heftig]

Since 0.25.4, a build using gcc -m32 (on x86_64) fails the test-enumerate test:

p11-kit: 'templ[i].ulValueLen != 0' not true at prepare_recursive_attribute

@ZoltanFridrich I think there's a problem with the recursive allocation during attribute loading. It should only recurse further if the current attribute is an array, not if the base attribute we're trying to load is an array, which it always is.
