sh: include linux/time_types.h for sockios

Using the socket ioctls on arch/sh (and only there) causes build time
problems when __kernel_old_timeval/__kernel_old_timespec are not already
visible to the compiler.

Add an explict include line for the header that defines these
structures.

Fixes: 8c709f9a0693 ("y2038: sh: remove timeval/timespec usage from headers")
Fixes: 0768e17073dc ("net: socket: implement 64-bit timestamps")
