selftests/bpf: Check that JMP32 pointer vs zero jumps are not predictedgrafted

Add jmp32_ptr_vs_zero_jne: the fall-through of the 32-bit compare, which
the verifier used to skip, contains an out of bounds map value access,
hence w/o the previous patch the program is accepted. See previous patch
for detailed description.

+	  This option provides support for the IndustryPack framework.  There
+	  are IndustryPack carrier boards, which interface another bus (such as
+	  PCI) to an IndustryPack bus, and IndustryPack modules, that are
+	  hosted on these buses.  While IndustryPack modules can provide a
+	  large variety of functionality, they are most often found in
+	  industrial control applications.
