soc/intel/skylake/romstage: Increase size of postcar stack

I increase the size oof the postcar stack to prevent a stack overflow
during the measured boot feature. After common string functions have
been moved from inline into .c file
(https://review.coreboot.org/c/coreboot/+/32901), I experienced a stack
overflow in the postcar stage while verifiying the romstage during
measured boot. To prevent this, the stack size should be increased. To
play it safe, it should be increased to 8 KiB - though this is open for
discussion.
