arch/x86: Adjust size of postcar stack
With VBOOT=y && VBOOT_MEASURED_BOOT=y message digest will be allocated from the stack and 1 KiB reserve used with the recent platforms was no longer sufficient. The comment of LZMA scratchpad consuming stack was obsolete for postcar, so these can be reduced to same 4 KiB.
