[PATCH] sbuild: Don't update apt database on every package build

[Uladzimir Bely <ubely@ilbers.de>]

By default, sbuild updates apt database beforethe build. It may cause
an inconsistency between apt databases for different packages built at
the different time if external (Debian) mirrors has updated recently.

With new changes, sbuild will rely on global apt state that was got
during debootstrap stage.

Local `isar-apt` repo will still be automatically updated while it is
passed via `--extra-repository=` argument.
