libglusterfs: Negate all but O_DIRECT flag if present on anon fds

        Backport of: http://review.gluster.org/14665

This is to prevent any unforeseen problems that might arise due to
writevs and readvs being wound with @flag parameter containing
O_TRUNC or O_APPEND especially wrt translators like sharding and ec
where O_TRUNC write or O_APPEND write on individual shards/fragments
is not the same as O_TRUNC write or O_APPEND write as expected by the
application.
