Top-level Makefile is still not managed by Automake (e.g. hand-made).
This is preparatory work. Other configure.ac files will be gradually
merged into the top-level one. After that we will be able to throw-away
the hand-made top-level Makefile and use Automake for everything.

The Python detection logic will be improved later when we start to use
top-level configure.ac to manage build completely. For now simple bump
is enough.

Mozldap is not used for some time now. We can remove
all traces of it.

AFAIK the complex logic for OpenLDAP detection should not be
necessary and -lldap_r -llber options should suffice.

Unfortunatelly OpenLDAP package does not ship
package config files so we have to hardcode flags.

Use package config instead of checking headers.
Package config is faster because it does not invoke compiler
and guarantees proper linking flags because these are provided
by package maintainer instead of hardcoded into build system.

libkrad does not have package config file so we keep the old way here.

The unit test framework check has not been used in freeipa for long time
(if ever) but there was still conditional check for this framework.
It just produced confusing warning:
    Without the 'CHECK' library, you will be unable
    to run all tests in the 'make check' suite
