[PATCH wip/dovetail 1/1] cobalt: Remove duplicate timespec/itimerspec copy helpers

[Florian Bezdeka]

The variant of such helpers which are using a temporary element on the
stack work in both worlds, so on systems with 4 and 8 byte time_t.
To keep the code as simple as possible we can remove the
__BITS_PER_LONG == 64 implementation.
