Add the new simple helper, LOCAL_ACTIVE(). True if crash examines the live kernel
on the same machine.
I do not really like to use MEMSRC_LOCAL; it would be better to define this helper
as ACTIVE() && !REMOTE_ACTIVE(), the last patch in series could set REM_LIVE_SYSTEM.
But this can't really work without other cleanups.
