Print ipa-ldap-updater errors during RPM upgrade

ipa-ldap-updater does a lot of essential LDAP changes and if it
fails, user may be surprised after the upgrade why things does not
work.

Modify ipa-ldap-updater to print ERROR logging messages by default
and modify RPM upgrade scriptlet to show these errors to user. Console
error messages are now formated in a more user-friendly way.

Information message stating that IPA is not configured and i.e. there
is nothing to be updated is not printer to stderr so that it does
not pop up for every freeipa-server package update when IPA is not
configured.
