aports: GNSS via forked Alpine libqmi + modemmanager

libqmi: the upstream-merged (!470, in no release yet) LOC Register Events
client-identification TLVs, taken verbatim from upstream main (532de37e).
modemmanager: the AFW engine unlock + Position Report derivation (!1463,
still draft upstream, review-hardened and verified on device). Both as
patches on Alpine's git-snapshot aports, pkgrel=100.
