s4:torture/vfs/fruit: expand test "setinfo eof stream"

o Adds checks verifying that after setting eof to 0 on a stream, a
  subsequent open gets ENOENT, before and after closing the handle that
  had been used to set eof to 0.

o Verify that a write to a handle succeeds after that handle has been
  used to set eof to 0 on a stream.
