The sysctl documentation states that the JIT is only available on
x86_64, which is no longer correct.
Update the list, and break it out to indicate which architectures
support the cBPF JIT (via HAVE_CBPF_JIT) or the eBPF JIT
(HAVE_EBPF_JIT).

This enables Berkeley Packet Filter Just in Time compiler.
-Currently supported on x86_64 architecture, bpf_jit provides a framework
-to speed packet filtering, the one used by tcpdump/libpcap for example.
+
+There are two flavors of JIT, the new eBPF JIT supported on:
+ - x86_64
+ - arm64
+ - ppc64
+ - sparc64
+ - mips64
+
+And the older cBPF JIT supported on:
+ - arm
+ - mips
+ - ppc
+ - sparc
+
+The BPF JIT provides a framework to speed packet filtering, the one used by
+tcpdump/libpcap for example.

Values :
0 - disable the JIT (default value)
1 - enable the JIT
