kselftest: vDSO: Fix accumulation of uninitialized ret when CLOCK_REALTIME is undefined
In the unlikely case that CLOCK_REALTIME is not defined, variable ret is
not initialized and further accumulation of return values to ret can leave
ret in an undefined state. Fix this by initialized ret to zero and changing
the assignment of ret to an accumulation for the CLOCK_REALTIME case.

kselftest: Extend vDSO selftest to clock_getres
The current version of the multiarch vDSO selftest verifies only
gettimeofday.
Extend the vDSO selftest to clock_getres, to verify that the
syscall and the vDSO library function return the same information.
The extension has been used to verify the hrtimer_resoltion fix.
