    test/ec: Fix spurious failures caused by self-heal

    The sha1sum of a file may update the access time of that file.
    If this happens while a brick is down, as it is forced in the
    test, that brick doesn't get the update, getting out of sync.

    When the brick is restarted, self-heal repairs the file, but
    the test shouldn't access brick contents until self-heal finishes.
    If this is combined with a kill of another brick before self-heal
    has finished repairing the file, the volume could become inaccessible.

    Since the purpose of these tests is only to check ec functionality
    (there is another test that checks self-heal), the test that corrupts
    the file has been removed.

    Additional checks to validate the state of the volume have been added
    to avoid some timing issues.
