Documentation: kmemleak: fix stale statements about scanning

Three statements in the "false positives/negatives" and "Limitations"
sections have never matched the code:

 - task stack scanning is on by default (kmemleak_stack_scan = 1), as
   the parameter list earlier in the same document already states;

 - MSECS_MIN_AGE has been 5000, not 1000, since the initial commit;

 - scanning is done by a periodic kthread. Reading the debugfs file
   only lists what the last scan found; kmemleak_open() calls
   seq_open() and never scans.
