kernel: the initramfs script takes over a default-config preset and checks each image (issue 1977, L7-L9)

Before mkinitcpio -P, a preset naming ALL_config="/etc/mkinitcpio.conf" is copied to the state's taken-over/ and loses that line (another ALL_config is left and named); after it, an image without kernel/x86/microcode/ in its first 64 KiB fails the unit and records nothing. The unit may write /etc/mkinitcpio.d. The README names no node. Tests: 1977/AC7, 1977/AC8; AC3/AC4 fixtures write images. Builds: L7, L8, L9 (issue 1977 note 4)
