Summary:
We now reads table properties in VersionSet::LogAndApply(), which requires options.db_paths to be set. But since ldb_cmd directly creates VersionSet without initialization db_paths, causing a seg fault. This patch fix it by initializing db_paths.
log_and_apply_bench still shows segfault, because table cache is nullptr in VersionSet created.
Test Plan: Run ldb dump_manifest which used to fail.
