[reltool] Just warn if same module occurs twice in .app file

OTP-9792

Earlier this would cause an error with reason
"Module xxx potentially included by two different applications: yyy and yyy."

This is now changed so it will only be a warning saying that the
module is duplicated in the .app file.
