Jacob Lalonde 353f75410a [LLDB] Add SI_USER and SI_KERNEL to Linux signals (#144800) ...

@dmpots and I were investigating a crash when he was developing LLDB
earlier. When I loaded the core I was surprised to see LLDB didn't have
information for the SI_CODE. Upon inspection we had an si_code of `128`,
which is the decimal of SI_KERNEL at `0x80`.

These were overlooked in my last addition of the negative si_codes, and
this patch adds SI_USER and SI_KERNEL to the list, covering us for all
the codes available to all signals.

I kept the code naming the same as what is defined in the Linux source
code. SI_KERNEL to my understanding usually indicates something went
awry in the Kernel itself, but I think adding that additional detail
would not be helpful to most users. @DavidSpickett I'd appreciate your
insight into that.
