initramfs: move gen_initramfs_list.sh from scripts/ to usr/
scripts/gen_initramfs_list.sh is only invoked from usr/Makefile.
Move it so that all tools to create initramfs are self-contained
in the usr/ directory.

-Usage:
-$0 [-o <file>] [-u <uid>] [-g <gid>] {-d | <cpio_source>} ...
-	-o <file>      Create compressed initramfs file named <file> using
-		       gen_init_cpio and compressor depending on the extension
-	-u <uid>       User ID to map to user ID 0 (root).
-		       <uid> is only meaningful if <cpio_source> is a
-		       directory.  "squash" forces all files to uid 0.
-	-g <gid>       Group ID to map to group ID 0 (root).
-		       <gid> is only meaningful if <cpio_source> is a
-		       directory.  "squash" forces all files to gid 0.
-	<cpio_source>  File list or directory for cpio archive.
-		       If <cpio_source> is a .cpio file it will be used
-		       as direct input to initramfs.
-	-d             Output the default cpio list.
-
-All options except -o and -l may be repeated and are interpreted
-sequentially and immediately.  -u and -g states are preserved across
-<cpio_source> options so an explicit "-u 0 -g 0" is required
-to reset the root/group mapping.
