Log Message:
Fix previous; hide userland ABI details for kernel as suggested by joerg:
http://mail-index.netbsd.org/source-changes-d/2020/06/21/msg012745.html
- Revive __lwp_settcb(), and call _lwp_setprivate(2) from it.
- Keep l_private opaque pointer for kernel; store raw value of %r2 in it.
In the previous commit message, I wrote,

but, it turned out to be wrong. mips stores a biased address, at least.
It is userland responsibility to interpret returned values from
lwp_getprivate(2).
