Writes invalid schroot config : jammy-security+main-amd64: Invalid name

[Scott Moser]

sbuild-launchpad-chroot is writing names (aliases) that are invalid per schroot.conf.
This causes failure of attempted sbuild.

$ sudo sbuild-launchpad-chroot create --name=jammy-amd64 --series=jammy --architecture=amd64
$ sbuild --dist=jammy --arch=amd64 --arch-all ../out/openssl_1.1.1f-1ubuntu2.16.1~22.04~sm0.dsc
