MINOR: promex: expose ST_I_PX_RATE (current_session_rate)

It has been requested to have the current_session_rate exposed at the
frontend level. For now only the per-process value was exposed
(ST_I_INF_SESS_RATE).

Thanks to the work done lately to merge promex and stat_cols_px[]
array, let's simply defined an .alt_name for the ST_I_PX_RATE metric in
order to have promex exposing it as current_session_rate for relevant
contexts.
