Correct load bias in symbolizer.

On Android 10, there is a bug in libunwindstack that would result in incorrect
relative pcs due to missing load bias. We can analyze the ELF file when
symbolizing, and if this happened, adjust the pc by the load_bias.


Test: symbolize Android 10 and Android 11 profile.
      For Android 10 profile, the load bias is corrected.
      For Android 11 profile, it is not.
