Introduce rate counter tx_stale_bursts

Browse Source 
This allows checking if there's timing issues on the downlink side
between osmo-bts-trx and osmo-trx. This counter is useful to find
information about osmo-bts-trx 'fn-advance' setting, since this counter
basically counts if burstrs from it arrived too late to osmo-trx.
