control/controlclient: move lastPrintMap field from Direct to mapSession

Browse Source 
It was a really a mutable field owned by mapSession that we didn't move
in earlier commits.

Once moved, it's then possible to de-func-ify the code and turn it into
a regular method rather than an installed optional hook.

Noticed while working to move map session lifetimes out of
Direct.sendMapRequest's single-HTTP-connection scope.
