(sending to the list because it contains the solution) TL;DR: compiling in refclock_local, but leaving it out of config disables sync

The drift file has been written out with zeros for a long time now.

--enable-lockclock wasn't set during compile, but this DID lead me to
making a useful discovery:
refclock_local was enabled as a compile-time option, probably from when
I was ensuring all Gentoo-user-accessible code paths compiled.
Turning off that got me a useful messages in the logs:

So improvements:
- BUG: figure out why refclock_local being simply compiled-in and not in the
config at all prevented sync.
- MAYBE: log if the clock would have been stepped but isn't because $reasons
- DEBUGGING: during startup AND version output, log what refclocks are
compiled-in
- DEBUGGING: log slewing changes
