Only call sqlite3_expanded_sql when it exists

Browse source 
Only print expanded SQLite statement, when expanding function exists. This is
required to not bump the minimum required Ubuntu version, since Ubuntu 16.04
doesn't ship SQLite 3.14 or above. SQLite introduced ``sqlite3_expanded_sql`
in 3.14, Ubuntu 16.04 packages 3.11.

Disabled weak linking on MSVC, since it isn't supported.
