pkg/report: skip crypto frames for KMSAN reports

This bug is at least one case where we merge several different KMSAN
reports because they end up being triggered in the same generic code:
https://syzkaller.appspot.com/bug?id=6290a184e96e8fb4b657700adcd243ef195113e1

Skip some common symbols from crypto/ so that the titles become more
specific.
