metrics: fix installation of metrics header

  If Jansson was found, the headers list is overwritten when including
rte_metrics_telemetry.h, which prevents rte_metrics.h from being
installed. This is now fixed to add to headers, rather than overwrite,
to allow both headers be installed when Jansson is present.
