migration: add has_postcopy savevm handler

Browse source 
Now postcopy-able states are recognized by not NULL
save_live_complete_postcopy handler. But when we have several different
postcopy-able states, it is not convenient. Ram postcopy may be
disabled, while some other postcopy enabled, in this case Ram state
should behave as it is not postcopy-able.

This patch add separate has_postcopy handler to specify behaviour of
savevm state.
