Subject: [PATCH] Use UNUSED wherever applicable in derive_input tests

Exhaustivity check:
```
<tests/suites/test_suite_psa_crypto.data awk -F: '$1=="derive_input" { for (step=1; step<=3; step++) { if ($(4*step-1) == "0") { if ($(4*step) != "UNUSED" || $(4*step+1) != "\"\"" || $(4*step+2) != "UNUSED") print NR, step, $(4*step), $(4*step+1), $(4*step+2) } } }'
```
