sssd: fix issue if build machine is Debian

The configure script guesses the target system from the host if no
--with-os= is set[1]. It is untrue if cross-compiling.

The guessed host operating system is used then to do specific things
fort target build.

The commit[2] passes the downstream debian option --install-layout=deb
to setup.py[3] if the host system is debian based, and thus, it raises
the error attached below as that debian-specific option[4] is not part
of the openembedded[5] world.

This sets the Fedora operating system thanks to the existing configure
option --with-os=fedora, that is relatively sain operating system for
the needs of openembedded.

Fixes:

Note: Upstream has introduced the "unknown" operating systemd with the
upcoming version 2.10.0[6][7]. The change can be backported.
