sys/time.h provides timeval, not timespec. It doesn't provide a forward
declaration of a struct timezone. Finally, it may make visible all
symbols provided by sys/select.h, so we might as well do that in case
some application relies on this optionally allowed behavior.
Provide timespec in time.h, and change the include to fix a resulting
compile error.
