Alexei Starovoitov ecc26ff830 selftests/bpf: make 'dubious pointer arithmetic' test useful
commit 31e95b61e172144bb2b626a291db1bdc0769275b upstream.

mostly revert the previous workaround and make
'dubious pointer arithmetic' test useful again.
Use (ptr - ptr) << const instead of ptr << const to generate large scalar.
The rest stays as before commit 2b36047e7889.
