[p2p] bump DEFAULT_MAX_ORPHANAGE_LATENCY_SCORE to 3,000

Browse Source 
For the default number of peers (125), allows each to relay a default
descendant package (up to 25-1=24 can be missing inputs) of small (9
inputs or fewer) transactions out of order.

This limit also gives acceptable bounds for worst case LimitOrphans iterations.

Functional tests aren't changed to check for larger cap because it would
make the runtime too long.

Also deletes the now-unused DEFAULT_MAX_ORPHAN_TRANSACTIONS.
