For oneapi compilers don't use -ftz for versions < 2022.

`icx -ftz hello.c` gives a warning for 2021 versions:

```
$ icx -ftz hello.c
icx: command line warning #10430: Unsupported command line options encountered
These options as listed are not supported.
For more information, use '-qnextgen-diag'.
option list:
        -ftz
```

So only use it for 2022 where it works.

One ftz test is then changed to 2022, the 2021 test removes ftz.
