systemd: Remove exporting special CPP

This is no more needed.
it was done long ago while systemd lived in meta-openembedded
http://lists.openembedded.org/pipermail/openembedded-commits/2012-August/141061.html
The accompanying patch has been applied to systemd already so we were
not needing to set CPP for sometime now.

as a nice side effect it helps compiling systemd with clang
