x86/vdso: Include vdso/processor.h

__vdso_getcpu is declared in a header but this is not included
before the definition, causing a W=1 warning:

arch/x86/entry/vdso/vgetcpu.c:13:1: error: no previous prototype for '__vdso_getcpu' [-Werror=missing-prototypes]
arch/x86/entry/vdso/vdso32/../vgetcpu.c:13:1: error: no previous prototype for '__vdso_getcpu' [-Werror=missing-prototypes]
