[OE-core] [PATCH 2/3] perf: add perf-trace feature

[tom.zanussi at linux.intel.com]

From: Tom Zanussi <tom.zanussi at linux.intel.com>

Add a new feature named 'perf-trace'.  Adding this into the
PERF_FEATURES variable in perf.inc will enable 'perf trace' support on
the target.  'perf trace' is meant to be perf's 'strace on steroids'
utility, and it also adds libaudit to the image, if perf is included
in an image.

If 'perf-trace' isn't named as a feature (the default), 'perf trace'
support will be disabled and unavailable.
