CTest: remove unreachable code and CTestTestMemcheckUnknown test

The memory checker command can't be quoted at this point, because previously it
has been tested that the given file exists, which will fail if the name is
quoted. The CTestTestMemcheckUnknown test aimed to test this case, has always
failed to do so and serves no useful purpose therefore.
