[PATCH v4 7/8] tests/sockopt-timestamp: Use the old time_t struct for old timestamps

[Alistair Francis]

The SO_TIMESTAMP_OLD returns a timeval that matches the struct
kernel_old_timeval_t instead of the struct timeval. This is different
on new 32-bit architectures (like RV32) where timeval uses 64-bit time_t
while kernel_old_timeval_t uses 32-bit.

To fix overflow errors let's case the data to a struct
kernel_old_timeval_t instead of the libc stuct timeval.
