Fix dangling pointer issue in LocalUpdatbleMaps
Libunwindstack would remove duplicated items and update the `prev_map`
during reparsing `/proc/self/maps`. But we leave `prev_real_map`
pointing toward a MapInfo that will be deleted soon. It will cause a
dangling pointer issue.
Add new tests to cover this dangling pointer issue.
