Fix classic flang version screen

RichBarton-Arm · bryanpkc · commit dd4d98479f82 · 2025-02-20T12:57:25.000-05:00
Version screen has been erroneously reporting as flang-new since LLVM 12

Cherry-pick note: Starting with LLVM 20, the --version option reports "flang"
out of the box. This commit only adds a test case to ensure that the
behaviour does not change for Classic Flang.
