Use pid == 1 and /sbin/init as tt->this_task instead, pc->program_pid can't
be used.
We could probably leave tt->this_task = NO_TASK, but we need to initialize
CURRENT_CONTEXT() anyway and we need something for refresh_context(), to me
"init" looks better than (say) FIRST_CONTEXT() == swapper/0.
However, this means that /init/sbin will be always reported as "active", see
the next patch.
