Document Helgrind limitation that old access stack traces have maximum 8 entries

#define N_FRAMES 8
(defined in libhb_core.c:3888)

implies that 'other thread' stack traces are limited to 8,
even with a bigger --num-callers.

=> document this in the manual to avoid that a user believes this is a
bug in the stack trace logic of Valgrind.
