Make mlbase images compatible with the GRID/Singularity (!25)
Add /alrb /cvmfs /afs /eos mount point
From Lukas Heinrich: Note that this is a hack as long as overlayfs is not widely on grid sites using singularity as a container runtime. For overlya-enabled runtimes (such as docker) missing mountpoint are created on demand. I hope we can remove this soon.
