Details

1. /etc/polkit-1/rules.d should be readable by the polkitd group but not owned by the polkitd user (the daemon should not be able to write its own config).
2. /usr/share/polkit-1/rules.d should be readable by everyone (these files aren't exactly secret) but again, not writeable by polkitd.

The correct PKGBUILD permissions commands are:

# Local config is secret
chown -R 0:102 "$pkgdir/etc/polkit-1/rules.d"
chmod -R u=rwX,g=rX,o=- "$pkgdir/etc/polkit-1/rules.d"

# Default configs aren't secret
chown -R 0:0 "$pkgdir/usr/share/polkit-1/rules.d"
chmod -R u=rwX,go=rX "$pkgdir/usr/share/polkit-1/rules.d"

I'm not so sure the package-supplied rules should be world-readable. Think of administrator-created packages, which aren't public.

That's reasonable. They are readable in Debian/Ubuntu but I can't think of any good reason they'd need to be. My main concern is that they shouldn't be writable by polkitd.
