bpf: Update sysctl documentation to list all supported architectures

Browse Source 
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
