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.
