gen_init_cpio: remove leading `/' from file names
When we extracted the generated cpio archive using "cpio -id" command,
it complained,
cpio: Removing leading `/' from member names
var/run
cpio: Removing leading `/' from member names
var/lib
cpio: Removing leading `/' from member names
var/lib/misc
It is worse with the latest "cpio" or "pax", which tries to overwrite
the host file system with the leading '/'.
So the leading '/' of file names should be removed. This is consistent
with the initramfs come with major distributions such as Fedora or
Debian, etc.
