This makes shellcheck more happy and the code more robust towards
changes.

Less stream lined targets like the NXP EVKs need a hand copied
dtb but the devkit doesn't so don't copy in this case.

root.sh: Only check for patched packages when installed

See merge request Librem5/image-builder!99

Not all architectures have all packages (e.g. we don't have
flash-kernel on amd64) so check if a package is installed at
all before checking if it's patched.

build-image: use latest instead of unstable by default

See merge request Librem5/image-builder!96

Makefile: Use devkit as default target

See merge request Librem5/image-builder!97

Check for patched packages

See merge request Librem5/image-builder!98

This makes sure we don't end up with broken images pulling newer
versions from Debian than we have.

This would ideally be checked in separate test step but until this is
there let's put it here rather than shipping broken images.

While imx6 is still nice we want a simple

    make

build a devkit image by default. Use the latest kernel as well
since we're not publishing to storage.puri.sm atm.

Dockerfile: install unzip

See merge request Librem5/image-builder!95

unzip is needed to to extract jenkins' kernel archive.

Generate additional boot image for eMMC boot hwpart

See merge request Librem5/image-builder!87

Read the `want_boot_image` board config value, and add the boot image
the the list if the value is 1.
The boot image generated by the build-image script will get compressed
and its SHA256 hash added to the sha256sums file.

Prepare the Makefile for producing more than one image, and fix small
issues along the way.

- Rename 'IMAGE' to 'IMAGES', and generate COMPRESSED from IMAGES (the
  '.xz' suffix is appended to every filename in IMAGE).
- Fix the image being rebuilt every time even when no change occurred by
  making the 'local.sh-link' prerequisite order-only.
- Make CHECKSUM depend on COMPRESSED so that the checksum file is
  updated if the images changed.
- Use variable STAMPFILE instead of repeating 'tmp/$(IMAGE).stamp'.
- Remove all .tmp file in the 'clean' target. This also eliminates a
  potentially dangerous 'rm -rf *'.

This commit adds support to build-image for building an additional boot
image containing U-boot and m4.bin.
This feature is enabled by the `want_boot_image` board config variable.

Use flash-image to install the dev kit kernel

Jenkins: Fix typo

See merge request Librem5/image-builder!84

kernel: Process defconfig files

See merge request Librem5/image-builder!83

Configs not residing in the kernel tree can be defconfigs too
if we run oldconfig afterwards.

This allows us to use trimmed defconfigs which are way easier to
maintain and compare.

This makes the overrides more useful
