Subject: [PATCH v3] x86,vdso: Fix vdso_install

The filenames are different now.  Inspired by a patch from
Sam Ravnborg.

Acked-by: Sam Ravnborg <sam@...nborg.org>
Reported-by: Josh Boyer <jwboyer@...oraproject.org>
Signed-off-by: Andy Lutomirski <luto@...capital.net>

I kept Sam's ack from v2, since v3 has only a trivial change.

Changes from v1: Remove core kbuild change
Changes from v2: Name the result .so files again, not .so.dbg
