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. Bug: 155511785 Test: libunwindstack_test Change-Id: I62e1b97bcb73f07e9349671f0b758f5ec9de16c0
