[MINOR] Remove flaky assert in TestInLineFileSystem

[yihua]

What is the purpose of the pull request

This PR removes the assert of FileStatus::getAccessTime which is flaky on rare occasions (the difference is in ms as shown below), since the access time can be changed when reading the file to get the file status for the expected and actual. This only affects testReadInlineFile().
