[PATCH 1/1] fix(schroot): only mount base-apt if enabled

["'Felix Moessbauer' via isar-users" <isar-users@googlegroups.com>]

On partial rebuilds we might work on rootfs that do not have the
/base-apt directory anymore. This currently fails, as we unconditionally
mount the /base-apt when creating the schroot. This happens when running
any imager_run command on such a chroot. We fix it by only mounting
base-apt if needed.
