Allow fixup of apex directories.

For some reason, apex directory structure in the symbols directory
is not the same as on device.

This means that a directory on device like:

  /apex/com.android.art/lib64/libart.so

Is really found in symbols as:

  /apex/com.google.android.art/lib64/libart.so

Modify the script to look in both places for libraries.

Bug: 206463081

Test: Verified that libart.so in a backtrace now finds the symbols
Test: libart.so.
