selftests/bpf: fix endianness issues in test_sysctl
A lot of test_sysctl sub-tests fail due to handling strings as a bunch
of immediate values in a little-endian-specific manner.
Fix by wrapping all immediates in bpf_ntohl and the new bpf_be64_to_cpu.
fixup_sysctl_value() dynamically writes an immediate, and thus should be
endianness-aware. Implement this by simply memcpy()ing the raw
user-provided value, since testcase endianness and bpf program
endianness match.
