pkg/report: skip all kmalloc/kcalloc frames

Initially I tried to skip kmalloc frames more carefully
to report proper test names in KASAN tests (338, 340).
But as the result we badly parsed a real report,
while nobody cares much about how we parse KASAN tests
that happen to contain "kmalloc" in test function name.
Skip all kmalloc frames now.
