Make sure record pattern synonym selectors are in scope in GHCi.
Beforehand, when a record pattern synonym was defined in GHCi
the selectors would not be in scope. This is because of `is_sub_bndr`
in `HscTypes.icExtendGblRdrEnv` was throwing away the selectors.
This was broken by the fix to #10520 but it is easy to resolve.
