When systemd is used inside an initramfs, it uses the presence of
`/etc/initrd-release` to detect when the system is in the initrd phase.
Otherwise `/etc/initrd-release` has the same format as
`/etc/os-release`.

Add `os-release-initrd` package to provide `/etc/initrd-release` as a
symlink to the os-release file. To avoid adding this file to the
`os-release` package, explicitly only add `/etc/os-release` to the
`os-release` package.
