Bug 1859177

Description of problem:

In environment where libsss_sudo is not installed, like in container but on host alike, ipa-server-install now fails to finish properly.

Version-Release number of selected component (if applicable):

pki-server-10.9.0-0.2.fc33.noarch
freeipa-server-4.8.7-1.fc33.x86_64

How reproducible:

Deterministic.

Steps to Reproduce:
1. dnf remove -y /usr/lib64/libsss_sudo.so
2. dnf install -y --setopt=install_weak_deps=False freeipa-server
3. ipa-server-install -U -r EXAMPLE.TEST -p Secret123 -a Secret123

Actual results:

  [4/5]: starting ipa-custodia 
  [5/5]: configuring ipa-custodia to start on boot
Done configuring ipa-custodia.
Configuring certificate server (pki-tomcatd). Estimated time: 3 minutes

The ipa-server-install command was successful

Additional info:

Either whatever component that requires / configures libsss_sudo to be present should hard-require it, or ideally sudo shouldn't be used by the installer.

This is a regression against Fedora 32.
