HHH-16255 Avoid confusing logs "Executing import script"

1. Only log this when we're actually executing the script, i.e. when
   the target is the database.
2. Log "Executing script" rather than "Executing import script" since
   sometimes we're executing a drop script
   ("jakarta.persistence.schema-generation.drop-script-source").
