[arch-releng] custmize_airootfs function

Am testing out gitlab mkarchiso and all seems fine except I am getting /etc/skel files put in /root? Rather than a users home directory? Files in /etc/skel should be for users rather than root. Archiso configs could easily ship with required files in /airootfs/root by default. If I turn off '#' out or disable function then /etc/skel files are not present any longer. They are present in both /root and /home/user folders?
