unix: add SOF_TIMESTAMPING_* flags on Linux

Add the SOF_TIMESTAMPING_* flags used to request different types of
timestamping operations. In

  err := unix.SetsockoptInt(fd, unix.SOL_SOCKET, unix.SO_TIMESTAMPING, val)

val is a mask of SOF_TIMESTAMPING_* values.

See https://www.kernel.org/doc/Documentation/networking/timestamping.txt
for more information.

Fixes golang/go#28173
