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.

This refines the previous commit by shutting down the daemon cleanly
at the end of the test (assuming the test was successful). It
repurposes the 'internal_exit' API for this, which was previously used
by the now defunct --enable-valgrind-daemon functionality.
This allows us to test the daemon running as a host process, allowing
us to meaningfully test it using valgrind.
This commit only adds a single test that check that the daemon starts
up, can be pinged, and exits.
