Update git submodules

* Update platform/external/perfetto from branch 'master'
  to acf4eedef8ec5c9c56016212b2b33a86cd6652fb
  - Merge "Fix LocalBinaryFinder when path includes base.apk"
  - Fix LocalBinaryFinder when path includes base.apk
    
    Symbolization has two differents modes:
    * PERFETTO_SYMBOLIZER_MODE=index, which scans all files in the build
      folders.
    * PERFETTO_SYMBOLIZER_MODE=find, the default, which tries some
      heuristics to find the file.
    Two of the heuristics for the "find" mode tried to remove "base.apk!"
    from the library name, but there was a bug that removed an extra
    character.
    
    This commit fixes the bug and adds tests for all the heuristics.
