random: vDSO: add a __vdso_getrandom prototype for all architectures
Without a prototype, we'll have to add a prototype for each architecture
implementing vDSO getrandom. As most architectures will likely have the
vDSO getrandom implemented in a near future, and we'd like to keep the
declarations compatible everywhere (to ease the libc implementor work),
we should really just have one copy of the prototype.
This also is what's already done inside of include/vdso/gettime.h for
those vDSO functions, so this continues that convention.
