dev-perl/DBD-SQLite: Bump to version 1.500.0

- EAPI6
- Moved the use of system-sqlite into a USE="system-sqlite" useflag,
  as compiling against all present versions of dev-db/sqlite results
  in test failres that don't occur with the native version.
  Said Useflag is also off by default for that reason.

Upstream:
- Updated to bundled SQLite 3.10.2
- Added a ReadOnly connection flag.
- General improvments in ::Constants conveniences.
- Some bugs fixed in savepoint handling
- allow_multiple_statements retains contents of unprepared_statements
