vm_core.h: Increase the Fiber stack size on powerpc64
Currently the Fiber stack size is small for powerpc64 and it causes
test/ruby/test_backtrace.rb test to break, since it is using a 8kb stack
size.
It breaks on powerpc64 due to the fact that a frame in the stack is
usually 50% bigger on powerpc64 compared to Intel, due to some
considerations:
* The powerpc64 minimum frame is 2x bigger than on Intel
* Powerpc has more registers that might be saved in the frame compared
to Intel.
I ran the same ruby test that is failing on both Intel and Powerpc, and
each Fiber frame is ~50% bigger on powerpc64 for every single lambda
function, thus, we need to increase the stack size on powerpc64 to
accomodate the same tests/applications.
This fixes bug#13757.
