Tezt: Use `tail -F' instead of `cat' with runners
 
`tail -F' is more reliable, because `-F' implies retrying.

When messing around with runners, I ran into scenarios where the `cat' call
would prematurly exit (typically when importing a snapshot from a remote),
which then would cause the daemon to hang when it tried to write in the pipe.

`tail -F' is often suggested as a way to ensure your pipe remains always
writable. Applying this suggestion fixes my issue.

One can convinces oneself that this approach is fine by running existing
scenarios from the `bin_testnet_scenarios' folder. Additionnally, from a
terminal

    mkfifo foo
    tail -F foo

and from another terminal

    echo bar > foo
    echo foobar > foo

will have the expected outcome, that is `bar' then `foobar' are printed by the
`tail' process.
