chore: mark some PAM profiles as seen in d/postinst

Mark PAM profiles krb5, sss and yourdev as "seen" in /var/lib/pam so
next execution of command /usr/sbin/pam-auth-update in interactive
mode will ignore the values of 'Default' properties.
This avoids the automatic selection of the sss profile, which conflicts
with the yourdev profile.
