listkey: display the size of the listkey payload in a debug message

This is a useful information to have in general and we already have debug
output related to listkeys. I'm planning to play around with massive amount of
phases roots and bookmarks so having this data in debug will be very useful.
This already got me to spot that one of the Logilab's review repo is exchanging
65KB of phases data during each exchanges.
