kernel: add linux-initramfs-tool as dep of linux-image package

[amazingfate]

Debian forky has toggled to dracut as its default initrd, and linux-initramfs-tool is a virtual packaged prodided by all alternatives like initramfs-tools/dracut. So add linux-initramfs-tool to dependency would make system with other initrd like dracut happy.

Poem

🐰 A choice blooms bright in dependency's hall,
Where initramfs-tools need not stand alone,
linux-initramfs-tool answers the call,
Two paths now open where once was one stone! ✨

Inline comments:
In `@lib/functions/compilation/kernel-debs.sh`:
- Line 268: The control file in kernel-debs.sh declares "Depends:
initramfs-tools | linux-initramfs-tool" but runtime logic in functions
image:initrd.sh (update-initramfs call and chmod at initrd.sh:125) and
distro-agnostic.sh (chmod of /etc/kernel/postinst.d/initramfs-tools at
distro-agnostic.sh:305) assumes initramfs-tools; update either by tightening the
dependency to only initramfs-tools (remove the alternative) or make the initrd
build flow provider-agnostic: detect which provider is installed
(initramfs-tools vs linux-initramfs-tool) and invoke the appropriate
commands/paths (replace hardcoded update-initramfs call and
/etc/kernel/postinst.d/initramfs-tools chmods with conditional logic), updating
functions image/initrd.sh and distro-agnostic.sh accordingly.
