Bug#768062: Does not take already-selected alternate dependencies into account

[Josh Triplett <josh@joshtriplett.org>]

Package: debootstrap
Version: 1.0.64
Severity: normal

Please see the analysis in bug 746578.

The essential package "init" has:
Depends: systemd-sysv | sysvinit-core | upstart

The test in bug 746578 involved a modified libpam-systemd that had:
Depends: systemd-shim (>= 8-2) | systemd-sysv

The test invoked debootstrap like this:
debootstrap --print-debs --no-check-gpg --include=libpam-systemd jessie $DIR $MIRROR

Given that set of constraints, debootstrap *should* install init,
systemd-sysv, libpam-systemd, and *not* systemd-shim, since systemd-sysv
already satisfies libpam-systemd's dependency.

In addition to figuring that out automatically, debootstrap should at
least have produced that result if given --exclude=systemd-shim, since
no dependency requires debootstrap to add that back in.
