Free X509_EXTENSIONs

Previously, we would leak these extensions as they are not freed by the
stack. An except from the `sk_TYPE_free` documentation:

    sk_TYPE_free() frees up the sk structure. It does not free up any
    elements of sk. After this call sk is no longer valid.

The fix is to drain the stack and free its elements before freeing the
stack. sk_TYPE_pop_free does this, so we use that instead.
