Title: #301: scripts, tests: explicitly set confdir in the rest of server code
This PR implements the stuff that was agreed on in later comments in
https://github.com/freeipa/freeipa/pull/280 and actually requested by @pvoborni.
Currently, I do not see the reason why this PR should not be accepted, if
IPA_CONFDIR is required in either of these scripts for some reason, we can
implement it later and add the justification to it.
