[roll] Roll fuchsia [fx set] Don't print "compiling fx set"

We now rebuild the fx-set executable whenever git HEAD changes. Given
that `fx set` only needs to be run at most once a day for most
workflows, we end up rebuilding the executable on nearly every run. That
diminishes the utility of printing the "compiling fx set" status message
because users will just become accustomed to the slight slowdown as it
will apply to every run – we originally added the log under the
assumption that we'd only have to recompile rarely.

At this point the log probably does more harm than good by exposing
potentially confusing implementation details to users and calling out
the compilation latency, which generally won't even be noticeable
compared to the 10-20 seconds that `fx set` normally takes.
