[LTP] [PATCH] sendfile08: disable this test on kernel less than 2.6.33

[Wanlong G. <gao...@cn...>]

After kernel commit cc56f7d, sendfile(2) can support any file refered
"out_fd" instead of only socket.
Since this test for general file refered "out_fd", so we disable this
test on the kernel less than 2.6.33.
