packaging: drop the aport; fp6-img installs the published apk
fp6-img no longer builds imsd from source: its images install the apk this
repo's package CI publishes to the registry (pinned version + sha256), so
the image and 'apk upgrade' carry the same binary and APKBUILD.binary is
the only imsd packaging left. The two payload files the aport carried
(kde-modem-daemon skel override, systemd preset) move up to packaging/,
where build-package.sh now takes them from.

# CI package build: cross-compile imsd for aarch64 with crafter-build (the
# README's "Cross-compiling" flow), run the test suite natively, and package
# the result via packaging/APKBUILD.binary. Expects an x86_64 Alpine
# environment with root — the workflow runs it in an alpine:edge job
# container on an ordinary runner. Root only installs packages and hands off
# to a scratch user: the sysroot is built with apk.static --usermode (which
# refuses root) and abuild wants a user too.
#
# Built packages land in /home/build/.local/share/abuild/*/aarch64/imsd*.apk;
# the workflow's publish step uploads them to the Forgejo Alpine registry.

# local rehearsals (file:// works).
