  2. link_test: remove AttachType from cgroup fixtures 

    Since the test is gated by haveProgAttach(), it should not specify AttachType,
which is a feature available as of 4.17.

Also, CGroupSKB doesn't require specifying AttachType.

  3. prog_test: remove map from TestProgramInstructions 

    Kernels up until 4.16 return kernel pointers in the constant field of map load
instructions and don't set the source register to pseudo values correctly. This
results in an incorrect Tag value calculation on the userspace side.

Remove the use of a map fd in TestProgramInstructions to fix the test between
kernel versions 4.13 and 4.16.
