IMPALA-6284: Mark the intermediate decimal avg struct as packed

We saw some failures on the exhaustive release build because the
compiler assumed that the pointer to the intermediate struct that is
used for computing decimal average was aligned.

To fix the problem, we mark the struct with a "packed" attribute so
that the compiler does not expect it to be aligned.

Testing:
- Ran the failing test locally on an release build and it passed.
