In testing other code, I stumbled across an exception when a user sets
PYTABLES_SYS_ATTR=False from openFile.
The following patch is one way to fix it (silences the exception), but I'm not
sure I like the behavior still. The error comes from a few lines below, where
it tries to set FILTERS anyway. Should FILTERS be conditional on
PYTABLES_SYS_ATTR too?

I prefer the following, which omits the pytables attribute FILTERS too, but I'm
not sure what will break (no failures with test_all light).
