[Buildroot] [git commit] fs: use a per-rootfs fakeroot script

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=48152408306a0dd06153f1816568036738c628d5
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

... and locate that script in a per-rootfs directory.

Just like for ROOTFS, this variable will leak down the dependency tree to
target-finalize and packages - But it doesn't matter as it isn't used
outside fs/.
