selftests/bpf: Fix casting error when cross-compiling test_verifier for 32-bit platforms
When cross-compiling test_verifier for 32-bit platforms, the casting error is shown below: test_verifier.c:1263:27: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast] 1263 | info.xlated_prog_insns = (__u64)*buf; | ^ cc1: all warnings being treated as errors Fix it by adding zero-extension for it.
