Maxim Cournoyer 35ae95061e system: Do not delete all nss-certs packages when they are the same object. ...

Calling 'delete' on the list of packages would delete *all* occurrences of a
given object, not just the first one.  This meant that if the user had
something like:

  (packages (cons nss-certs %base-packages))

In their operating system declaration, no nss-certs would end up in the final
list.  To guard against this, guard against this by checking that more than
one nss-certs package exist even after deduplication.

* gnu/system.scm (operating-system-packages): Guard against deleting all
nss-certs when a single nss-certs package object is listed multiple times.
