Keep only wp_die polyfill among driver patches

temporary_table_exists → false triggers a Turso sqlite3_finalize
deadlock during PHP GC (PHPUnit hangs at 504/667). Leave the method
unmodified; the 250 sqlite_temp_master errors are preferable to a
hung CI job. Deadlock is in turso_sqlite3 — would need a fix in
upstream Turso, not something patchable via sed.
