Rationale:
cpio -t alone cannot extract initrd past early cpio (microcode) in most packed initrd.
unpack_initramfs.sh already under master comes to the rescue, but its usage up to today was limited to pass firmware blobs to final OS under boards/librem_mini_v2
Debian OSes (and probably others) need to have cryptroot/crypttab overriden directly, otherwise generic generation of crypttab is not enough.
Extracting crypttab and overriding directly what is desired by final OS and exposed into /boot/initrd is the way to go otherwise hacking on top of hacks.
This brings default packed modules under Heads to 5 modules, which needs to be deactivate in board configs if undesired:
user@heads-tests-deb12:~/heads$ grep -Rn "?= y" modules/ | grep -v MUSL
modules/zlib:1:CONFIG_ZLIB ?= y
modules/zstd:3:CONFIG_ZSTD ?= y
modules/exfatprogs:2:CONFIG_EXFATPROGS ?= y
modules/busybox:2:CONFIG_BUSYBOX ?= y
modules/e2fsprogs:2:CONFIG_E2FSPROGS ?= y
They're the same other than a TRACE, combine them. Use busybox
insmod since the insmod script uses bash, we don't need the TPM PCRs on
legacy-flash-boards.
Remove PCR4 extend, these boards lack TPM configuration. Update ROM
example name.

- legacy-flash boards have a single purpose: to flash BIOS region through flashrom.
- They do not need bash nor have space for it in their 4mb defined coreboot CBFS region
Test build to have legacy boards builds under osresearch#1292
- Add 4.19 under modules/coreboot
- point all 4.13 boards to 4.19
- adapt x230 FHD/EDP patch under patches/coreboot-4.19/0001-x230-fhd-variant.patch (poked upstream to fix patch under https://review.coreboot.org/c/coreboot/+/28950)
- correct versioning info under .circleci/config/yml
