x86/vdso: Provide getcpu for x86-32.
Wire up __vdso_getcpu() for x86-32. The 64bit version is reused with trivial modifications. Contrary to vclock_gettime.c there is no requirement to fake any defines in the case of 32bit VDSO on a 64bit kernel because the GDT entry from which the CPU and node information is read is always the native one. Adopt vdso_getcpu.c by: - removing the unneeded time* header files which lead to compile errors for 32bit. - adding segment.h which provides vdso_read_cpunode() and the defines required by it.
