pgbench has #defines for number of branches, tellers, and accounts. There

are used to populate the tables with -i, but when running actual benchmark
it has values separately hard-coded in the query metacommands.  This patch
makes the metacommands obtain their values from the relevant #defines.

Patch provided by Jeff Janes.
