LibCoredump: Fix use-after-free in Backtrace::object_info_for_region()

Browse source 
The first line was creating a StringView object with region name. Then,
if the path didn't start with '/', it had assigned a String made from a
temporary LexicalPath join result.

This fixes the bug that only main executable's frames were displayed.
