CREATE DATABASE: make LOCALE apply to all collation providers.

Browse Source 
For CREATE DATABASE, make LOCALE parameter apply regardless of the
provider used. Also affects initdb and createdb --locale arguments.

Previously, LOCALE (and --locale) only affected the database default
collation when using the libc provider.
