[klibc 08/43] klibc: default initramfs content stored in usr/initramfs.default

["H. Peter Anvin" <hpa@zytor.com>]

Harcoding default content of initramfs in the gen_initramfs_list.sh
script seems ackward. Move it to a file named:
usr/initramfs.default

This also fixes a small bug when no arguments was passed to
CONFIG_INITRAMFS_SOURCE (-d was passed twice to the script)

Idea and bug report from: "H. Peter Anvin" <hpa@zytor.com>
