packaging: own the apk aport (transferred from fp6-img); version 0.3.1

packaging/aport/ is now the canonical apk packaging, moved here from
fp6-img so the daemon and its package live and version together —
fp6-img's build.sh consumes this directory instead of carrying its own
copy (it pins _commit and generates the source tarball, as before).

0.3.1 ships the ims-pdn-up hardening (visible mmcli errors, registration
gate, configurable ip-type) and the TimeoutStartSec bump that goes with
it.
