sqldb: add SQLStrValid helper

Browse Source 
The SQL* helpers are meant to always set the `Valid` field of the
sql.Null* type to true. Otherwise they cannot be used to set a valid,
empty field. However, we dont want to break the behaviour of the
existing SQLStr helper and so this commit adds a new helper with the
desired functionality.
