Fix #13968 by consulting isBuiltInOcc_maybe
Summary:
We were unconditionally reporting `Illegal binding of built-in syntax`
in an error message, but this error doesn't make sense in certain Template
Haskell scenarios which can trigger it. Let's give a more sensible error
message by first checking if the name we're binding really is built-in syntax,
using the handy `isBuiltInOcc_maybe` function.
