testsuite: tweak error messages for new Show instance

be3d7f661968a7b8c6751c0be3bf23e703b32c3e added Show
instance for Callstack.

That made a couple of error messages to drift as:

             instance Show Ordering -- Defined in ‘GHC.Show’
             instance Show Integer -- Defined in ‘GHC.Show’
             ...plus 23 others
    -        ...plus 20 instances involving out-of-scope types
    +        ...plus 21 instances involving out-of-scope types
