drop_monitor: Make timestamps y2038 safe

Browse Source 
Timestamps are currently communicated to user space as 'struct
timespec', which is not considered y2038 safe since it uses a 32-bit
signed value for seconds.

Fix this while the API is still not part of any official kernel release
by using 64-bit nanoseconds timestamps instead.

Fixes: ca30707dee ("drop_monitor: Add packet alert mode")
Fixes: 5e58109b1e ("drop_monitor: Add support for packet alert mode for hardware drops")
