migration from custom namedValue to driver.NamedValue

build is failed because support driver.NamedValue appeared in Go 1.8.
I think this is not important, because if the project has an old version of Go, they will not update the library version.

Hi, thanks for the changes to support gorm and others, though backward compatibility is very important, if it can be preserved, it should. I do not want to create the v2 just for this minor change, which can be made backward compatible in general. Just move the functions related to files before go 1.8 and after.

@l3pp4rd, unfortunately, as you suggested, it will not work, because gorm inside has checks sql.NamedArg structure.

I doubt that those who did not upgrade Go to version 1.8+ will start updating the DATA-DOG/go-sqlmock library. It's time to stop supporting mammoths :)
