ipatests: add test ensuring SIDs are generated for new installs
    
    The standard installer now configures all the items needed
    for SID generation. Add a new test with the following scenario:
    - install IPA server
    - create an active user
    - ensure the user's entry has an attribute ipantsecurityidentifier
    - ensure that the kerberos ticket for the user contains PAC data
    by using the utility ipa-print-pac
