system: Set "rootfstype" for tmpfs root file system.
This commit adds configuration for tmpfs root file system. Since there's no
file system information in boot parameters, not all tmpfs cases are handled.
* gnu/system.scm (bootable-kernel-arguments): Check root file system for tmpfs
and set "rootfstype".
