Kernel: Add `sid` and `pgid` to `Credentials`

There are places in the kernel that would like to have access
to `pgid` credentials in certain circumstances.

I haven't found any use cases for `sid` yet, but `sid` and `pgid` are
both changed with `sys$setpgid`, so it seemed sensical to add it.

In Linux, `man 7 credentials` also mentions both the session id and
process group id, so this isn't unprecedented.
