lib/cloner.c enlarge cloner stack size

After the tst_res() interface was fixed
not to interleave messages while called
from several threads by preparing the
message in buffer created on the stack
some testcases (./shmem_2nstest clone)
started to hang because of stack overflow
so this patch increases stack size for
cloned process from four to six pages.
