Medium: Logging: Sanitize and centrally define the log facility used by various subsystems

In changeset 1f454f857ee8 Alan changed the CRM to default to LOG_DAEMON.
Most other places also default to LOG_DAEMON, with notable exceptions being
ha_logd and cts.

So... make ha_logd and cts default to use LOG_DAEMON and define the value to
use centrally in configure.in

As a bonus, remove calls to hb->llc_ops->get_logfacility() which is redundant now
that cl_inherit_logging_environment() exists.
