When CONFIG_INITRAMFS_SOURCE is empty, the Makefile passes the -d
option to gen_initramfs.sh to create the default initramfs, which
contains /dev, /dev/console, and /root.
This commit simplifies the default behavior; remove the -d option,
and add the default cpio list.

Currently, this script is run twice, for the dependency list, and then
for the cpio archive.
The first one is re-run every time although its build log is suppressed
so nobody notices it.
Make it work more efficiently by generating the cpio and the dependency
list at the same time.

The comments in usr/Makefile wrongly refer to the script name (twice).
Line 37:
# The dependency list is generated by gen_initramfs.sh -l
Line 54:
# 4) Arguments to gen_initramfs.sh changes
There does not exist such a script.
I was going to fix the comments, but after some consideration, I thought
"gen_initramfs.sh" would be more suitable than "gen_initramfs_list.sh"
because it generates an initramfs image in the common usage.
The script generates a list that can be fed to gen_init_cpio only when
it is directly run without -o or -l option.
