Misc fixes about hardcoding of paths

This patchset mainly fixes several hardcoding problems.

There's a bug in Yocto's bugzilla:
https://bugzilla.yoctoproject.org/show_bug.cgi?id=7040
Bug 7040 - Support for /usr merge (à la systemd and Fedora)

I did some investigation and made it work for core-image-sato-sdk.

The solution is divided into two parts. One part is a custom layer which has a custom distro file and a few bbappend files for base-files, busybox, etc. I think the bbappend files are a little hacky and not suitable for OE. The other part is this patchset. It fixes several hardcoding problems in OE. I think this part is suitable for OE. That's why I sent it out.
