[PATCH RFC] insane.bbclass: add buildpaths_cmake and buildpaths_pkgconfig checks

[Mikko Rapeli <mikko.rapeli@bmw.de>]

And enable them by default as ERROR_QA. Reason is that
absolute build directory paths in CMake .cmake modules
and in pkg-config .pc files cause recipe builds to escape
their recipe specific sysroots and triggers hard to debug
and timing sensitive build failures. It's better to fail
early.

A failure from sumo version of libical looks like:

ERROR: libical-2.0.0-r0 do_package_qa: QA Issue: CMake module /work/i586-poky-linux/libical/2.0.0-r0/packages-split/libical-dev/usr/lib/cmake/LibIcal/LibIcalTargets-noconfig.cmake contains reference to tmpdir which causes build raceconditions between recipes [buildpaths_cmake]
ERROR: libical-2.0.0-r0 do_package_qa: QA run found fatal errors. Please consider fixing them.
ERROR: libical-2.0.0-r0 do_package_qa: Function failed: do_package_qa
ERROR: Logfile of failure stored in: /home/builder/src/yocto/poky/build/tmp/work/i586-poky-linux/libical/2.0.0-r0/temp/log.do_package_qa.4934
NOTE: recipe libical-2.0.0-r0: task do_package_qa: Failed
ERROR: Task (/home/builder/src/yocto/poky/meta/recipes-support/libical/libical_2.0.0.bb:do_package_qa) failed with exit code '1'

For some reason libical from poky master branch is not affected.
