TT#61152 Fix c621c376: fix apt option Acquire::Retries for mmdebstrap

Otherwise installation fails on CE/PRO/Carrier:
> Executing: mmdebstrap --arch amd64  --no-merged-usr --variant=minbase \
>    --include=systemd,systemd-sysv,init,isc-dhcp-client,ifupdown \
>    --aptopt='Acquire::Retries "3"'  buster /mnt/debootstrap.4597 https://debian.sipwise.com/debian/
> I: The option --no-merged-usr is a no-op. It only exists for compatibility with some debootstrap wrappers.
> I: automatically chosen mode: root
> I: chroot architecture amd64 is equal to the host's architecture
> I: Reading sources.list from standard input...
> E: invalid mirror: /mnt/debootstrap.4597
>  ESC[31;01m-> Failed (rc=25)ESC[0m
