mmdebstrap creates the chroot with the -amd64 suffix hardcoded in the path

My package uses instructions here to add a private repo (aptly job of another package on salsa).

variables:
  SALSA_CI_EXTRA_REPOSITORY_SOURCES: debian/salsa-ci.extra_repository.sources
  # Extra variable for https urls
  SALSA_CI_MMDEBSTRAP_EXTRA_ARGS: --include=ca-certificates

It works fine for the amd64 build, but not for the i386

It seems like SALSA_CI_MMDEBSTRAP_EXTRA_ARGS: --include=ca-certificates is only honored for the mmdebstrap amd64 image, not for the i386 image.

I have this error because ca-certificates is not installed in the i386 image.

Also note that the log says that there is no chroot found for i386, thus it creates it from scratch.
