[PATCH v3 2/2] cmd: ufetch: only show comma separator if there was a previous feature

[Quentin Schulz <foss+uboot@0leil.net>]

From: Quentin Schulz <quentin.schulz@cherry.de>

Currently, if NET is disabled, the next feature to be printed will start
with a comma and a space which is not pretty. Add the comma and
whitespace only when a previous feature has already been shown.
