### Issue
ipaserver/install/adtrustinstance.py provides the function check_inst() which ensures that the Samba packages are installed and that /usr/share/ipa/smb.conf.empty exists which means the adtrust sub-package is installed.

Unfortunately it only prints the output and does not log it making reviewing a user-provided log insufficient to know exactly what is wrong.

#### Steps to Reproduce
1. Add --setup-adtrust to the ipa-server-install CLI without having the freeipa-server-trust-ad package installed

#### Actual behavior
AD Trust requires the 'freeipa-server-trust-ad' package
Please install the package and start the installation again
Aborting installation.

The server install log contains only "Aborting installation."

#### Expected behavior
The server log also contains the printed messsage.
