databases/sqlite3: Update to 3.39

ChangeLog: https://www.sqlite.org/releaselog/3_39_0.html

• Add (long overdue) support for RIGHT and FULL OUTER JOIN.
• Add new binary comparison operators IS NOT DISTINCT FROM and IS DISTINCT FROM that are equivalent to IS and IS NOT, respective, for compatibility with PostgreSQL and SQL standards.
• Add a new return code (value "3") from the sqlite3_vtab_distinct() interface that indicates a query that has both DISTINCT and ORDER BY clauses.
• Added the sqlite3_db_name() interface.
• The unix os interface resolves all symbolic links in database filenames to create a canonical name for the database before the file is opened.
• Defer materializing views until the materialization is actually needed, thus avoiding unnecessary work if the materialization turns out to never be used.
• The HAVING clause of a SELECT statement is now allowed on any aggregate query, even queries that do not have a GROUP BY clause.
• Many microoptimizations collectively reduce CPU cycles by about 2.3%.
