Simpleperf: fix some unknown symbols for report result.
Using debug shared libraries in /usr/lib/debug on linux host.
Match ip addresses with symbols by symbols' virtual addresses instead of
file offsets in elf file. Because symbols' file offsets in debug shared
libraries are different from those in original shared libraries.
Fix overlapped maps.
