[OE-core] [PATCH 1/2] initramfs-live-install: avoid using grub.d/40_custom

[rongqing.li at windriver.com]

From: Robert Yang <liezhi.yang at windriver.com>

We have this in recipes-bsp/grub/grub/40_custom:

[snip]
menuentry "Linux" {
    set root=(hd0,1)
    linux /vmlinuz root=__ROOTFS__ rw __CONSOLE__ __VIDEO_MODE__ __VGA_MODE__ quiet
}
[snip]

These lines are only for initrdscripts/files/init-install.sh, the side
effect is that it would make the target's grub-mkconfig doesn't work
well since the 40_custom will be installed to /etc/grub.d/40_custom, the
grub-mkconfig will run the 40_custom, and there will always be a
'menuentry "Linux"' menu in grub.cfg no matter it is valid or not, we
can do this in init-install.sh rather than grub to fix the problem,
which is also much simpler.
