[PATCH 2/4] sbuild-chroot: Skip initramfs generation while installing build dependencies

["'Jan Kiszka' via isar-users" <isar-users@googlegroups.com>]

From: Jan Kiszka <jan.kiszka@siemens.com>

We have no need for an initramfs while building packages. Therefore,
keep the update-initramfs stub inside the sbuild-chroots so that they
are working also while build dependencies are installed.
