Since we have aports-qa-bot now set up to ping maintainers, let's make
it explicit that I maintain these packages.
Clean up CODEOWNERS as well for my entries which anyways contain my
username which is not used on gitlab.p.o.
[ci:skip-vercheck] # even though Maintainer line is embedded in .apk, it
doesn't make sense to mass rebuild these packages just for that.

Now as boot-deploy allows us to generate both boot.img and extlinux.conf
at the same time, enable generating the config for all msm8226 since it
will be used in the future lk2nd release. boot.img is still kept to keep
compatibility with current lk2nd releases and to allow system recovery
with fastboot when required.
