    Disable `-fdefer-out-of-scope-variables` in ghci.
    
    We have already disabled `-fdefer-type-errors` and
    `-fdefer-typed-holes` in ghci.
    This patch disables `-fdefer-out-of-scope-variables` as well.
    
    Fixes Trac #15259, as well as #14963.
    
    Test Plan: make test TEST="T15259 T14963a T14963b T14963c"
