Use reasonable SQLite3 module version

Since PECL/sqlite3 has been moved to ext/sqlite3 in 2008, the SQLite3
module version is hardcoded to `0.7-dev`. It doesn't appear to make
much sense to have an own module version for a bundled extensions, but
as other code might rely on it, we don't remove the constant but rather
make it an alias of the PHP version.
