TT#62000 Install dirmngr package before puppet run

Initially dirmngr package was installed to allow running apt-key inside
deployment.sh to install puppetlabs key. Then after moving puppetlabs
key to local file package installation was removed. But we still need it
for successful first puppet run that also uses apt-key. Otherwise there
is the error: 'Could not find a suitable provider for apt_key'. Puppet
also installs dirmngr package but in such case only the second puppet run
will be successful so we need to install the package before the very
first puppet run.
