Subject: logcollect: collect firmware version not BV

Log collections showed wrong firmware version.  Cause was use of the BV
tag instead of openprom/model.  The BV tag is the base version of
firmware used in manufacturing.  openprom/model is the current version
of firmware.

Also separated null trimming into a separate method.
