initramfs-live-install*: fix the "install" boot option

The install boot option was giving the following error when one tried to
install the live image on a  permanent storage of a BSP.

cat: write error Invalid argument
Installation image failed
sh: can't access tty: job control turned off

Further digging into the issue, found out that the install script was trying
to do this:
 cat /proc/mounts > /etc/mtab

And in the base-files recipe the /etc/mtab is made soft link to /proc/mounts.
So the cat command was failing to write on /etc/mtab. As the contents of
the /proc/mounts is already reflected in the /etc/mtab file due to the
symlink-ing, there is no need for this step to recreate /etc/mtab in the
install script. So just removing this unnecessary step, which solves the
install issue of the live images.

Fixes this bug:
[YOCTO #4229]
