global: switch to coarse ktime
Coarse ktime is broken until [1] in 5.2 and kernels without the
backport, so we use fallback code there.
The fallback code has also been improved significantly. It now only uses
slower clocks on kernels < 3.17, at the expense of some accuracy we're
not overly concerned about.
