By positioning this after extracting the initramfs-extra archive, we can
allow udev to exist in the -extra archive and not have any size impact
on the base initramfs archive.
Any hook that needs udev in the initramfs can get that support, provided
that the hook lists udev requirements in the .files config for it.
At the moment, mkinitfs loads some file system modules always (ext4),
some dynamically (brtfs) and some not at all (f2fs, vfat), expecting
them to be built-in.
To support generic kernels (e.g. from Alpine) properly, use the
partition type detection for both boot and root partition and always
load the necessary modules before mounting.
This replaces the previous `udevadm test` hack with a combination of
`udevd`, `udevadm trigger` and `udevadm settle` in order to coldplug all
available devices and make them available for use via libinput / unl0kr.

unudhcpd is a lightweight dhcp server that effectively implements static
assignment of a single IP on an interface regardless of client MAC, with
no lease. The end result is that a system connected to a pmOS device via
usb networking should always get an IP, and always get one very quickly.
This adds a new dependency on this dhcp server, and starts it in initfs.

This replaces the mkinitfs script with a re-write (in Go). The
re-written mkinitfs will atomically replace the initfs in /boot, check
for free space before doing so, and try to do whatever it can to not
leave the system in an unbootable state by botching the initfs
creation/installation.
pmb:cross-native with go cross compiling doesn't work exactly, it makes
the correct binary, but on Alpine go uses -buildmode=pie which creates a
dynamic thing, and the interpreter is wrong (e.g. it it set to use the
host arch's interpreter, like /lib/ld-musl-x86_64 even though
GOARCH=arm64)
The init.sh script is no longer a template, "initramfs-extra" is used.
