Build: properly integrate ipasetup.py into build system

AC_CONFIG_FILES in configure.ac works well only with Makefiles.
Other files have to be handled by Makefile.am so depedencies
are tracked properly.

There is a problem that Python sub-directories depend on ipasetup.py
which is one level above the sub-directory. This means that depedencies
are the other way around that expected. This is being worked around
using hack from
