[OE-core] [PATCH 7/9] perf: add perf-scripting MACHINE_FEATURE

[tom.zanussi at intel.com]

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

Add a new MACHINE_FEATURE named 'perf-scripting'.  Adding this into
any machine configuration will enable perf scripting on the target,
which will turn on all the language bindings currently aavailable in
perf (Perl and Python), if perf is included in an image.

If 'perf-scripting' isn't named as a feature (the default), all perf
language bindings will be disabled and unavailable.
