init-install.sh: remove unnecessary udev rules file to avoid error messages

/etc/udev/scripts/mount.sh is removed by init-install-efi.sh, but the
udev rules file which specifies the invocation of this script is not
removed, thus causing the error message during a live install:

/etc/udev/scripts/mount.sh: No such file or directory

The /etc/udev/rules/automount.rules no longer works once the mount.sh
script is removed. Remove it to avoid the error message.
