add nonstandard timespec/timeval conversion macros in sys/time.h
these are poorly designed (illogical argument order) and even poorly implemented (brace issues) on glibc, but unfortunately some software is using them. we could consider removing them again in the future at some point if they're documented as deprecated, but for now the simplest thing to do is just to provide them under _GNU_SOURCE.
