Thomas Weißschuh 258b37c6e6 vdso: Gate VDSO_GETRANDOM behind HAVE_GENERIC_VDSO
All architectures which want to implement getrandom() in the vDSO need to
use the generic vDSO library.

This is a generic implementation of gettimeofday vdso.
Each architecture that enables this feature has to
provide the fallback implementation.

Select to add multiplication overflow protection to the VDSO
time getter functions for the price of an extra conditional
