Andrey Borzenkov 1de4d79bf5 build-sys: add Mandriva distribution support 
This merges several separate patches that I carry as part of
Mandriva systemd RPM. They touch those parts that are very
unlikely to be changed in near future and do not impose any
functionality change for systemd core. I also think it is
useful for troubleshooting to have real distribution name in
system logs, espicially when someone reports problem upstream.

The patch looks bigger than sum of replaced patches because

- previous patches were applied on top of distro=fedora, now
I need to add all those bits for distro=mandriva as well

- part of patch was done as spec file magic, but it seems more
logical to ship all these bits together
