Fix small memory leak in partial-aggregate deserialization functions.

A deserialize function's result is short-lived data during partial
aggregation, since we're just going to pass it to the combine function
and then it's of no use anymore.  However, the built-in deserialize
functions allocated their results in the aggregate state context,
resulting in a query-lifespan memory leak.  It's probably not possible for
this to amount to anything much at present, since the number of leaked
results would only be the number of worker processes.  But it might become
a problem in future.  To fix, don't use the same convenience subroutine for
setting up results that the aggregate transition functions use.
