On large sites cron runs into memory and performance problems.

This patch refactors xmlsitemap_generate_chunk, the place that call xmlsitemap_get_path_alias(). It overrides the query which collects aliases.

Looking at tests, this patch introduced a short array syntax, which will not work on older PHP still supported by this module. Classic array need to be used here.
