Instead of hardcoding the location of perl (assuming it is installed in /usr), use /usr/bin/env to run it, and thus picking it from $PATH. This makes it possible to run these scripts also on installations with perl in a different prefix than /usr. Also, given that we want enable warnings on scripts, turn the -w previously in shebang to explicit "use warnings;" in scripts which didn't have it before.
