tools headers: Update linux/vdso.h and grab a copy of vdso/const.h

To get in line with:

  8165b57 ("linux/const.h: Extract common header for vDSO")

And silence this tools/perf/ build warning:

  Warning: Kernel ABI header at 'tools/include/linux/const.h' differs from latest version at 'include/linux/const.h'
  diff -u tools/include/linux/const.h include/linux/const.h
