Fix and simplify checkmetrics make target (#1731) 

The checkmetrics target currently uses promtool v2.5.0 which doesn't
include many improvements done over the time. This change also
simplifies the promtool installation, avoiding a temporary directory by
extracting the file directly to the target destination.
