get_system_config() already parsed the whole system section but returned
only a slice of it, so netOrk had no IST side for three AP-profile fields
and could not compare them at all — the fields were editable, stored and
silently ineffective.
Adds:
* syslog_remote / syslog_ip / syslog_port / syslog_proto — read from the
system section that was already being parsed. log_remote gates the
others: OpenWrt ships nothing without it, so a leftover log_ip must
not read as an active target.
* luci_enabled — from the uhttpd init script rather than its listener
config, so the answer stays "is the web UI served" and re-enabling
restores whatever was configured before.
* bridge_stp — None when there is no br-ap at all, which is a different
statement from "bridge without STP" and has to stay distinguishable.
