fs/common: Create initial console device

Browse Source 
A /dev/console node must be present in rootfs when the Linux kernel
boots otherwise the kernel will print the following warning:
"Warning: unable to open an initial console"

This is because when we use an initramfs the /dev directory is not
populated at this point. This can cause problems when a program
(e.g ldso with early debugging enabled) opens a standard file
descriptor for read/write before these descriptors are actually
created by the init process later on.
