  Check only rootfs as filesystem type

When detecting if rootfs is on ramfs instead of checking "- rootfs
rootfs" which is the " - <file_system> <device>" information only check
the file system type. This is due to a change introduced in kernel where
ramfs file system doesn't set the device to "rootfs" but instead mark it
as "none". By making sure we only check for "rootfs" as the file system
name we also offer backward compatibility with earlier kernels as well.

The kernel commit that introduced this change was
