Subject: [PATCH] systemd: give up on "dev" output for now

There are too many references to ${systemd}/foo,
and the savings would be on the order of 100 kB.

Also:
 - fix udev install paths (again), hopefully OK now;
 - fix one RPATH
 - clean libudev propagation
 - pick examples/ changes from staging (probably lost by some auto-merge)
