vdso: Add prototype for __vdso_clock_getres_time64()
For consistency with __vdso_clock_gettime64() there should also be a
64-bit variant of clock_getres(). This will allow the extension of
CONFIG_COMPAT_32BIT_TIME to the vDSO and finally the removal of 32-bit
time types from the kernel and UAPI. The generic vDSO library already
provides nearly all necessary building blocks for architectures to
provide this function. Only a prototype is missing.
Add the prototype to the generic header so architectures can start
providing this function.
