scripts/mysql: updated 'gw' and 'lcr' table definitions

- Updated 'gw' and 'lcr' MySQL table definitions.
- No idea if a schema exists somewhere where sr tables are
  auto-generated.
- The tables are assumed to have versions 10 and 3, respectively
  although there is no 'version' table in sr database.
