[gentoo-catalyst] Support for custom memory settings in AUFS

On the original livedvd which I initially implemented AUFS support to
allow users to use of emerge, I implemented the ability to append
"aufs_mem=X" into the kernel since the default was to use tmpfs without
"-o size" option. Attached is a patch that will reintroduce this to
catalyst.
