legacy handlers need a bigger buffer

In the original ipmi execution queue, handlers were passed a larger
buffer. The current code was only passing in the configured channel
size, or 64 if no size was configured. This is too small and leads
to buffer overflows for responses greater than 64 bytes.

This brings the buffer sizes up to a point that matches the legacy
code and to a size that is larger than any of IPMI standard transport
sizes.

Tested: used a bogus handler to create a large response and found that
        the entire response was returned.
