added capability to ignore client-provided timestamp on unix sockets and
made this mode the default; this was needed, as some programs (e.g.
sshd) log with inconsistent timezone information, what messes up the
local logs (which by default don't even contain time zone information).
This seems to be consistent with what sysklogd did for the past four
years. Alternate behaviour may be desirable if gateway-like processes
send messages via the local log slot - in this case, it can be enabled
via the $InputUnixListenSocketIgnoreMsgTimestamp and
$SystemLogSocketIgnoreMsgTimestamp config directives
