pkg/report: improve uvm_fault reports on OpenBSD
Some reports[1] does not include a symbol but rather an address in the "Stopped at" line. There's unfortunately no useful context to add to the title so make them generic instead. [1] https://syzkaller.appspot.com/bug?id=3e44d0b128fd8d6826e4d0044baadcfc02ba7125
