slices: update TestIssue68488 to avoid false positives
Fixes #74387
Even tho we are abusing unsafe.SliceData a bit here it's probably fine;
in case this test fail, it means some memory alias is happening
which is not good for GC purposes.
We don't care about false keep alives for stack locations tho.
