perf sched: Use PTHREAD_STACK_MIN to avoid pthread_attr_setstacksize() fail

on ppc64:
/usr/include/bits/local_lim.h:#define PTHREAD_STACK_MIN 131072

therefore following set of commands:

gives:
perf.2.6.37test: builtin-sched.c:493: create_tasks: Assertion `!(err)' failed.

So make sure we do not set stack size lower than PTHREAD_STACK_MIN.
