initramfs: use /etc/ntp.conf (with ntpd.conf symlink), fix CPIO redirection, add customization logs

• scripts/lib/initramfs.sh: write /etc/ntp.conf, symlink ntpd.conf if absent; compute absolute output path before cd so cpio|xz redirection works; emit verification logs around initramfs_finalize_customization()

• config/zinit/init/ntpd.sh: robust parsing of kernel ntp=, safe defaults, and launch BusyBox ntpd with -p servers
