Remove actor-alive?.

`actor-alive?' was actully returning the boolean opposite of what it
should have.  It turns out we don't need it anyway, so removed.

* 8sync/actors.scm (condition-signalled?, actor-alive?): Removed.
* 8sync/repl.scm (repl-manager-main-loop): Just loop on #t, since
daydream won't resume anyway if our actor dies.
