installer.sh: install tarantool using exact version

Sometimes a distro contains newer tarantool than a repository offers. However it is counter-intuitive when, say, you want to install 1.10, but 2.5 comes without any warnings.

I overcome the problem for tarantool-php CI this way: tarantool/tarantool-php@176d49f . Here I also verify the installed version against the requested one.

Now stable 2.6 is out and the problem is not so hot.

Aside of this, @artembo said that he increased priority of the installed repositories (both for Debian based and RHEL allied distributions) in installer.sh, so it should work correctly even for 1.10.

I guess the problem persists with manual installation instructions for 1.10.

This should become less painful with upcoming release policy renew: we will not offer 'unstable releases' as releases anymore. So distro maintainer will pick up a correct release (not newer than on our website). OTOH, it solves the problem only for a most recent series (2.6 for now, series 2 in the future), but not for, say, 1.10. Manual instructions still require an update.
