selftests/bpf: fix "alu with different scalars 1" on s390
BPF_LDX_MEM is used to load the least significant byte of the retrieved test_val.index, however, on big-endian machines it ends up retrieving the most significant byte. Change the test to load the whole int in order to make it endianness-independent. Signed-off-by: Ilya Leoshkevich <iii@linux.ibm.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org>
