[flang][test] Move two tests around in DisabledFiles.cmake

[klausler]

Summary

Move two tests into the section of tests for which flang emits
valid errors for usage that gfortran accepts. Neither of them
would be suitable as extensions -- one could change the behavior
of existing code, and the other is ambiguous.
