    selftests/bpf: Fix casting error when cross-compiling test_verifier for 32-bit platforms
    
    [ Upstream commit 0811664da064c6d7ca64c02f5579f758a007e52d ]
    
    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.
