sha-1 has known collision issues, which may not be readily
exploitable yet (in our context), but we should ideally use
a more secure method for checking file integrity.
therefore, use sha-2 (sha512sum) for checking files. this is
slower than sha-1, but checksum verification is only a minor
part of what lbmk does, so the overall effect on build times
is quite negligible.

Tested on a Nucleo-F042K6.
That has an onboard stlink:
`st-flash --format ihex write bin/serprog_stm32/serprog_nucleo-f042k6.hex`
The usb port used for flashing is separate, its is exposed on
the pin header instead. Check boards/nucleo-f042k6.h for usb pinout.

target.cfg can now specify e.g.
grub_timeout=20
this would then be inserted as timeout.cfg in cbfs,
containing the instruction:
set timeout=20
HP laptops need a bit of extra time, due to the delay
caused by the EC bug workaround deployed in GRUB
desktops in general need extra time. this too is set to
10s, like the HP laptops.
only insert timeout.cfg if actually needed (declared in
target.cfg), otherwise grub.cfg will default to 5s

for example, the beep sound in debian's installer needs
this module.
the cute ding in the arch/artix menu also needs it

now under coreboot mainboards, target.cfg can specify
a background. if not specified, the 1280x800 one is
assumed, and used by default. it can be overridden.
the path should be relative to:
config/grub/background/

this causes a saving of about 131KB uncompressed, when
i tested. we don't need mach kernel support. nobody will
ever use it.

this causes a 6.7% decrease in the payload size
these file systems are microsoft(fat, ntfs) or mostly
oldschool amiga and beos file systems
also remove minix modules, and some old linux file
systems that nobody will use in 2023

it doesn't really make sense for them to be under
blobs/ - nominally, they are blobs, but they are
well-understood data files containing config data,
that is easily parsed by tools like ich9show or
ifdtool (and tools like bincfg or nvmutil)
blobs/ has been re-purposed: this directory no longer
exists in lbmk, but it is created (and on .gitignore)
when needed, by blobutil
thus, the blobs/ directory shall only contain vendor
files, and only those files that libreboot scrubs from
releases. therefore, build/release/src can (and has
been) simplified; it currently copies just the ifd and
gbe files from blobs/, selectively, and this logic is
quite error prone, requiring maintenance. now, the
build/release/src script simply copies config/ (which
only ever contains distributable files) and entirely
ignores the blobs/ directory
the blob download script already creates the required
directory, except for the sch5545 download; this is
now fixed
lbmk code size is slightly smaller, due to this patch
