Install all packages in one go and don't copy pacman.conf to airootfs

configs/{baseline,releng}/build.sh:
Copy custom files to airootfs before installing packages.
Instead of calling `mkarchiso init`, list all required packages in packages.x86_64 and install them all at once with `mkarchiso install`. The mkdir command which `mkarchiso init` performs is now done by make_custom_airootfs.

configs/releng/build.sh:
Don't copy configs/releng/pacman.conf to airootfs, it is only meant to provide a unmodified pacman.conf durring pacstrap. In airootfs, an unmodified /etc/pacman.conf will be installed with the pacman package.
