nixos: Add zram swap module

This allows you to use the Linux kernel's built-in compressed memory as
swap space functionality.

It is recommended to enable only for kernel 3.14 (which is when zram came out of
the staging drivers area) or higher.
Scatter output hook

This hook allows to scatter files in $out to multiple outputs.
For "bin" and "doc" outputs there are prefefined default masks, but
they can be overriden by setting files_<outname>, for example:

files_bin = [ "/bin/*" "/lib/libexec/" ];

To make an effect hook must be specified in buildInputs.
