[inset-area] Use 'stretch' for justify-self / align-self in tests

The current tests did not expect the proposed 'normal' alignment
behavior. Adjust the tests to be alignment-agnostic so that they will
still pass with alignment-behavior changed. Alignments different from
'normal' and 'stretch' uses fit-content sizing.
