net-p2p/tribler: Fix extract for DF and unmask installation commands

On the last update, the logic for the post-extract command was changed,
which broke the target on DF.  This version works on all platforms.

While here, rework the do-install target so that the commands aren't
suppressed.  Also simplify it.
