config/coreboot-qemu-tpm*.config: save back to oldconfig format

- make BOARD=qemu-coreboot-whiptail-tpm1 coreboot.modify_and_save_oldconfig_in_place
- make BOARD=qemu-coreboot-whiptail-tpm2 coreboot.modify_and_save_oldconfig_in_place

Now we see errors in coreboot happening at boot related to referred bootsplash images:

[ERROR]  memalign(boundary=8, size=1179648): failed: Tried to round up free_mem_ptr 0x7fece968 to 0x7ffee968
[ERROR]  but free_mem_end_ptr is 0x7ffcca70
[ERROR]  Error! memalign: Out of memory (free_mem_ptr >= free_mem_end_ptr)Bootsplash could not be decoded. jpeg_decode returned 1.
[INFO ]  CBFS: Found 'fallback/payload' @0x38000 size 0x7a0780 in mcache @0x7fffeb78
