We do not want this going forward as we will be changing the wallpaper
on a bi-yearly basis and we do not want to have perform shotgun surgery
every time we do so.
[ci:skip-build]: already built successfully in CI
Previously, the grep command would detect the /usr/bin/share string
inside of the .ci/grep.sh file, so only check the device folder to
avoid this. Other folders shouldn't contain any kernels anyway.
[ci:skip-build]: Everything but linux-postmarketos-qcom-sm7150
built fine in CI, and linux-postmarketos-qcom-sm7150 built fine
locally. Building linux-postmarketos-qcom-sm7150 via the CI failed
because it took over 3 hours so the CI timed out.
Note that the URLs in these scripts are not only for information, but
they are also used as marker by pmbootstrap so it knows these are
compatible with 'pmbootstrap ci'. I just fixed the typo in the
pmbootstrap code as well and made a new release, use pmbootstrap 1.50.0
or above to have it recognize these scripts with 'pmbootstrap ci' again.
Adjust all CI scripts that make use of .ci/common.py to
'pmbootstrap ci'. Move all scripts that are not direct entry points to
running CI scripts to .ci/lib.
Comment out the dtb check, as it is failing. Apparently it didn't run
properly before. Let's fix this after this CI change is done.
Split out the grep for CHANGEME into a separate .ci/grep.sh script, as
it's not related to shellcheck and also there's another grep check that
I'll move there in a follow-up patch.
