osmo-trx: log to stderr on signal received
Since osmo-trx it's a big multithreaded process and shutdown sequence
can be complex, better use stderr to log signal received events to make
sure log is outputted straigh away and not buffered. In general stdout
is usually line-buffered, but buffering strategy can be more
conservative if output is for instance redirected to a file.
