rpc: bumpfee, improve doc for 'reduce_output' arg
The current argument name and description are dangerous as it don't
describe the case where the user selects the recipient output as the
change address. This one could end up been increased by the inputs
minus outputs remainder. Which, when bumpfee adds new inputs
to the transaction, leads the process to send more coins to the
recipient. Which is not what the user would expect from a
'reduce_output' param naming.
