heapprofd: Fix outdated log message

At the beginning, heapprofd could work in two modes on android:
* Central, where each app connects to the central heapprofd daemon.
* Fork, where each app starts its own heapprofd daemon.

On android user builds, only fork mode was supported. An app would try
to connect to the central heapprofd daemon, it would fail and then it
would start its own heapprofd daemon in fork mode.

The log message made sense.

Then, central mode started to be supported on user builds and fork mode
was removed on android.

Since https://r.android.com/1536299, the log message doesn't make sense
anymore.
