main/postmarketos-installkernel: modernize

Reorders the keys to match newapkbuild and fixed
the provider, since the current logic made it
always be considered a lower provider priority
than the Alpine installkernel. Also moved the
location of the installed binary to not need
to replace Alpine's installkernel.
