SPLIT_64 missing again

This line shouldn't be removed.

#define SPLIT_64(value) (int) (((__u64) (value)) >> 32), (int) (((__u64) (value)) & 0xffffffff)

was removed again in timetrace.h after commit 89b1e99, which leads to a compilation failure.

Drat; sorry about that. I will push a fix shortly. This keeps happening because I do my testing with a modified Linux kernel, one of whose header files includes a kernel version of timetrace.h that defines SPLIT_64. Thus it compiled for me. I don't currently have an easy way to compile Homa with an "out of the box" kernel... I need to fix that.
