meta-phosphor: cmake packages: add pkgconfig
With the latest Yocto we see failures:
```
17:14:36 | CMake Error at /home/jenkins-op/workspace/ci-openbmc/distro/ubuntu/label/docker-builder/target/tiogapass/build/work/arm1176jzs-openbmc-linux-gnueabi/phosphor-ipmi-ipmb/0.1+gitAUTOINC+8227626764-r0/recipe-sysroot-native/usr/share/cmake-3.21/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
17:14:36 | Could NOT find PkgConfig (missing: PKG_CONFIG_EXECUTABLE)
```
Add the correct inherit for ipmb-ipmb. Pre-emptively add for any
recipe which does 'inherit cmake'.
