Modify the library lookup code to try and find the various places
that a library might really exist in the symbols directory. This
is for atest which can run executables in different locations
than the actual where the symbolized file exists.
Test: Ran using /data/local/tmp, /data/local/tests,
Test: /data/local/tests/vendor, /data/local/tests/unrestricted and
Test: verified the correct library was found.
Test: Used tombstones crash data and verified all libraries
Test: still found properly.
Test: Ran atest CtsBionicTestCases and verified the symbolized
Test: binary could be found using a real tombstone crash.
Test: Did the same as above, but changed the path in the tombstone
Test: crash data from /data/local/tmp to /data/local/tests and
Test: /data/local/tests/unrestricted.
