Subject: um: Fix out-of-tree build

From: Richard Weinberger <richard@nod.at>

commit 0b5aedfe0e6654ec54f35109e1929a1cf7fc4cdd upstream.

Commit 30b11ee9a (um: Remove copy&paste code from init.h)
uncovered an issue wrt. out-of-tree builds.
For out-of-tree builds, we must not rely on relative paths.
Before 30b11ee9a it worked by chance as no host code included
generated header files.
