Use read streams in CREATE DATABASE when STRATEGY=WAL_LOG.

Use read streams in CREATE DATABASE when STRATEGY=WAL_LOG.

While this doesn't significantly change runtime now, it arranges for
STRATEGY=WAL_LOG to benefit automatically from future optimizations to
the read_stream subsystem. For large tables in the template database,
this does read 16x as many bytes per system call. Platforms with high
per-call overhead, if any, may see an immediate benefit.
