Fix locations given to ident in `let%xyz ident in ..`

This fixes a regression introduced in #5392, which adds the `let poly_`
syntax. Adding `poly_flag` to the let-pun case of `let_binding_body`
means `$loc` includes `poly_flag`, so `$loc($2)` should be passed to
`mkpatvar` and `ghexpvar` instead.

Unlike `rec` and `mutable`, the `poly_` flag is attached to idents
rather than let bindings. For example, `let%map poly_ x and poly_ y in ..`
is valid syntax, but `let%map rec x and rec y in ..` is not. Hence why
`poly_` is parsed in a differently from `rec` and `mutable`.
