Subject: [PATCH] debian: don't call dconf if it isn't installed

The dconf package isn't required by qubes-core-agent - the package ships
a configuration for it, useful if user have it installed for other
reasons. Don't try to rebuild dconf database if dconf isn't installed -
avoid misleading error message.

Fixes QubesOS/qubes-issues#3492
