Subject: [PATCH] volume-basic-test.sh: switch to .tplg parsing to test
 topologies v2

Until now this test was "screen-scraping" amixer output. This was not
compatible with v2 topologies which means the test was always SKIP for
everything developped on the main branch. Switch to parsing topologies
to extract volume kcontrols.

Fixes: #1069, see also discussion in earlier attempt #1068.
