[PATCH 1/3] unit/avrcp: Add /TP/CFG/BV-01-C test

[Andrei Emeltchenko <Andrei.Emeltchenko.news@gmail.com>]

From: Andrei Emeltchenko <andrei.emeltchenko@intel.com>

Test verifies that the get capabilities command issued from the
Controller. For that we add the command to avrcp-lib and it will be used
in AVRCP later.
