linux: make cpu_times consistently be milliseconds

On Linux, cpu_times have been calculated differently to all other
platforms for a while. Other platforms (FreeBSD, Mac, Windows) are all
in milliseconds, but Linux has been returning values ten times larger.

libuv has not previously documented what unit cpu_times uses, even
though NodeJS did - as milliseconds.

Here we're both documenting that the cpu_times are indeed in
milliseconds, and fixing the inconsistency on Linux.
