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.
