Subject: [PATCH] core/iwasm/interpreter/wasm_loader.c: remove an extra
 validation (#2845)

* Empty names are spec-wise valid.
* As we ignore unknown custom sections anyway, it's safe to
  accept empty names here.
* Currently, the problem is not exposed on our CI because
   the wabt version used there is a bit old.
