[Fortran] Disable pr32601.f03

[clementval]

llvm/llvm-project#107353 will relax the check when -pedantic is not enabled. -std=f2003 is not supported in flang. Disable the test until we have a way to add flags.

We don't allow changes to the actual tests in this suite. Trying to find a way to add/remove flags so such tests can be run is on my list of things to do.

For now, there are two options:

1. Disable this test. You can add it to the FAILING section of Fortran/gfortran/regression/DisabledFiles.cmake with a comment indicating why it has been disabled.

2. Disable this test and add a similar one to Fortran/UnitTests. There are a couple of examples of this such as Fortran/UnitTests/assign-goto.

See my previous comment on what needs to be changed. Thanks.

Thank you. I was not aware that we want to keep the original test as is. I'll update this patch.

Thanks for making the change, Valentin. :-)
