mod_proxy_hcheck: don't pile up health checks.  PR 63010.

Prevent health checks from running for a worker until the last one is fully
finished, to avoid making things worse (memory growth, #connections, ..).

This is done by zeroing worker->s->updated before scheduling the worker in the
threadpool, and resetting the time when it's finished. The scheduler then does
nothing if worker->s->updated is zero.

Also, to save some apr_time_now() calls when !HC_USE_THREADS, *baton->now is
updated in the callback and reused by the scheduler.
