The only purpose of legacy flash boards is to be flashed over vendor
firmware using an exploit, to then flash non-maximized Heads firmware.
They are never upgraded to another legacy flash build, and they move
the coreboot ROM from the build directory, so don't build an update
package for those boards.

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
