cd: enable tarantool repo for rpmbuild/debuild

There are distributions, where tarantool is in base repositories (such
as Fedora 30-34 or Ubuntu Focal). There are ones, where it is in
semi-official repos such as EPEL (CentOS 7/8). There are ones, where we
have no tarantool package at all (or have only old tarantool-lts as in
Ubuntu Bionic).

It seems meaningful to enable the tarantool repository everywhere and
don't depend on presence of a tarantool package in distribution base
repositories.

The repository is enabled using the installer.sh script: see [1] for
details. Aside of just enabling the repo it configures a package manager
(apt-get/yum/dnf) to prefer a package from our repository even when it
has lower version. So we'll build against latest 1.10 on all
distributions, it looks as the good side effect: unification.

Worked around a problem with pinned tarantool package and unpinned
tarantool-dev, see [2].
