Default policy: reduce default mempool expiry time

Reduces DEFAULT_MEMPOOL_EXPIRY from 336 hours to 24 hours.
Motivation is that while blocks are empty, un-relayable tx are
stuck in mempools for a long time and effectively locking utxo
for 2 weeks until they can be respent, if no RBF opt-in was
performed (most wallet implementations do not do RBF opt-in.)
As the expectation is that block space will not be fully utilized
for the foreseeable future, and therefore, as long as this is the
case, no valid transaction should ever live in the mempool for
more than a couple of minutes.

This default setting can be overridden with the -mempoolexpiry
parameter by individual node operators to a value (expressed
in hours) that makes the most sense for the use cases the node
serves.
