eudev: fix redefinition of usec_t and nsec_t. 

usec_t and nsec_t are defined twice (src/libudev/{util.h,path-util.h}).
This raises an error when using GCC 4.5, but not with later versions!
This patch fixes the issue by gathering the time-related functions and
definitions to time-util.[ch], as in upstream systemd.

This patch has been sent to upstream.

Fixes http://autobuild.buildroot.net/results/060/0605f279abfdfc837f6973f2898ed7ee39f2b8d1/

Subject: [PATCH] libudev: Fix redefinition of usec_t and nsec_t.
The type definitions usec_t and nsec_t are defined twice: in
path-util.h and util.h.
time-util.h and time-util.c now gather the time-related functions and
definitions (as in upstream systemd).
