[PATCH] have lb_chroot_hacks to build initrd only from chroot

[Luigi Capriotti <l.capriotti@xbmc.org>]

Hello,

Please accept this patch which address the issue of lb_chroot_hacks 
building an initrd image with kernel version from host system.

The rationale is that "update_initramfs -k all" builds an initrd with 
the kernel version of the build host, which may be different from the 
kernel versions in the chroot.

The patch does that by iterating on chroot/lib/modules and calling 
update_initramfs several times specifying the kernel version.

Cheers,

Luigi Capriotti
