selftests: xsk: Add test UNALIGNED_INV_DESC_4K1_FRAME_SIZE
Add unaligned descriptor test for frame size of 4001. Using an odd frame
size ensures that the end of the UMEM is not near a page boundary. This
allows testing descriptors that staddle the end of the UMEM but not a
page.
This test used to fail without the previous commit ("xsk: Fix unaligned
descriptor validation").
