[hardknott][PATCH 05/10] cmake.bbclass: remove ${B} before cmake_do_configure

["Anuj Mittal" <anuj.mittal@intel.com>]

From: Kai Kang <kai.kang@windriver.com>

It is fallible to remove ${B} in directory ${B} itself. And it does fail
when call bitbake by third-party wrapper script.

Use flag 'cleandirs' to remove ${B} first if build out of source tree.
