Precise exceeds loading timeout on RPi 3B+

[krisgesling]

Describe the bug
From techoneer on Mycroft Chat:

I noticed that ever since the latest auto update, my picroft on a Rpi 3B+ seems to fail to use precise listener. It tries to use it but then throws a "precise took too long to start" error in the logs and falls back to pocketsphinx which is not very good. It still seems to do this on a fresh install that autoupdated.

The only config changes were to the play commands to get USB audio to work.

Expected behavior
Precise should load within the hotword factory timeout of 10 seconds - or we need to extend that timeout.

Log files
This is from the voice.log. Seems like it actually loads initially soon after boot, then again 2 minutes later but that time it gives the "taking too long" message after 10 seconds and loads pocketsphinx instead
