Support profiling of shared libs embedded in APKs.
Some APKs contain shared libraries that the linker handles
by mmap'ing directly from their APKs (if the library is
uncompressed and the proper manifest flag is set). With
this patch simpleperf now breaks out samples on a per-li
basis and reports the name of the lib within the APK.
Example output:
Cmdline: /system/xbin/simpleperf record -a sleep 30
Samples: 140672 of event 'cpu-cycles'
Event count: 84111474884
