um, x86: Fix vDSO build

Commit 663b55b9b39 ("x86: Delete non-required instances of include <linux/init.h>")
broke the UML build.

  arch/x86/um/vdso/vdso.S: Assembler messages:
  arch/x86/um/vdso/vdso.S:2: Error: no such instruction: `__initdata'
  arch/x86/um/vdso/vdso.S:9: Error: no such instruction: `__finit'

UML's vDSO needs linux/init.h.
