Fix exception when path not found.
Add a default return value in a call in the GetLibraryByBuildId()
function to avoid an exception if a file cannot be found in the
symbol directory.
Bug: 216232380
Test: Ran the input from the bug. Verified without the change, the
Test: exception occurs and with the fix, no exception.
