Alpine's abuild is soon going to complain if an APKBUILD has more than
one "Maintainer:" listed. Work around it by renaming the additional
maintainers to "Co-Maintainer:". While at it, move the devicepkg reference
link to the top in device-xiaomi-santoni for consistency.
In postmarketOS, we require at least two maintainers for devices in
main, therefore it does not make sense to drop additional maintainers
from the file.
In Alpine, this change was made because pkgs.alpinelinux.org apparently
can't handle more than one maintainer. I looked into it, and it would
require a database change to add it there, so it does not seem worth the
effort. I also thought about extending abuild to add an environment
variable to skip the check, but then the package would not build with
plain abuild without using the env var.
