To avoid altering any currently existing callers, we continue on with
the calculation regardless of overflow. This also matches the behavior
of GCC's __builtin_add_overflow().

We added this utility for vulkan where all timeouts are given as
uint64_t values. We can switch from signed to unsigned as this is the
only user and if we ever deal with signed integers somewhere else
we'll have to be careful to use the corresponding
timespec_(add|sub)_msec and always pass absolute values.
