Remove PRAGMA case_sensitive_like — unsupported by SQLite drop-in

The SQLite integration drop-in intercepts all $wpdb->query() calls
and translates MySQL to SQLite. PRAGMA is not a MySQL statement, so
the translator rejects it with "Unknown query type: PRAGMA".

Removing this is safe: on SQLite, all columns already use the PHP
processing path (due to the REGEXP fallback), and PHP's str_replace
handles case-sensitivity correctly regardless of LIKE behavior.
